A line with a slope of 2 passes through the point (1,9). What is its equation in
slope-Intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

So, the numbers that would go in the blanks would be 2 and 7, respectively.
The slope intercept form of the line that passes through the point (1, 9) and has the slope 2 is y = 2x + 7.
What is slope intercept form of the line?The slope intercept form of the line is:
y - y₁ = m (x - x₁)
Given that the point that the line passes through is: (1, 9)
The slope of the line is: m = 2
Substitute the values in the equation, we get;
y - 9 = 2 ( x - 1)
y - 9 = 2x - 2
y = 2x + 7
Therefore, we get that, the slope intercept form of the line that passes through the point (1, 9) and has the slope 2 is y = 2x + 7.
So, the numbers that would be in the blanks would be 2 and 7, respectively.

Please I really need your help
Answers
Answer:
The discriminant of the quadratic equation is 0
Step-by-step explanation:
Here, we want to calculate the discriminant of the given quadratic equation
Mathematically, we have the discriminant calculated by the following formula;
D = b^2 - 4ac
where;
b represents the coefficient of x which is -2
a is the coefficient of x^2 which is 1/7
c is the last number which is 7
Substituting these values;
D = (-2)^2 -4(1/7)(7)
D = 4 - 4
D = 0

find the value of the variable
Answers
I believe Z is equivalent to 1.
Explanation:
The side with the variable must be less than the side containing 3. That means 1.5+Z would have to be less that 3. That also mean Z has to be less than 1.5 so that 15+Z can be less than 3. So the answer could be anything between 0 and 1.4 and I just settled on 1 because its the only whole number between the two.

Answers
Answer: 16cm
Step-by-step explanation:
l = 4w
2l + 2w = p

10w = 40
w = 4 cm

It's the last option
Step-by-step explanation:
The angles of a triangle will always be 180°.
so you do 38.2+52.7=90.9
180-90.9= 89.1
180-38.2-52.7= 89.1
A triangle should add up to 180. Just a clue if you would need help with any other problems with triangles. :)
6.) Find the measure of a.
115°
Answers
Answer:
65 degrees :)
Step-by-step explanation:
If you have 115 degrees, and you know triangles are always 180 degrees in total, then you have to subtract 115 from 180 to get your answer for what the measures are. 180-115=65
So it's 65 degrees.

Step-by-step explanation:
y - y1 = m( x - x1)
y - 3 = 2 (x + 4)
( -4, 3)
Answer:
(- 4, 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
y - 3 = 2(x + 4) ← is in point- slope form
with slope m = 2 and (a, b ) = (- 4, 3 )

what's 875,098 to the nearest 100 rounded?
Answers
Answer:
the answer to the problem is 875,100
Answer:
875,100Step-by-step explanation:
When we round to a particular place, we will use a few simple rules.
First, let's highlight the place value we're rounding to.
875,098
Next, we look at the number behind the highlighted number, in this case the tens place. If the number is less than 5, the highlighted place value will stay the same. If the number is 5 or above, the highlighted place value increases by 1. In this case, we round 0 up to 1, since there was a 9 in the tens place. We then add zeros for the tens and ones place, since we rounded out of those.

Find an expression which represents the difference when (2 + 4y) is subtracted
from (-8x + 3y) in simplest terms.
Answers
Answer:
-8x - y - 2
Step-by-step explanation:
(-8x + 3y) - (2 + 4y)
Change this to addition, but change the signs in the second parentheses:
(-8x + 3y) + (-2 - 4y)
Add like terms:
-8x - y - 2
So, the difference is -8x - y - 2
= -8x + 3y - 2 - 4y
= -8x + 3y - 4y - 2
= -8x - y - 2
