Consider the following pair of equations: y = x + 4 y = −5x − 2 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
(-1, 3)
Step-by-step explanation:
to solve using substitution, you have to know the value of either x or y. in this example, they gave you the value of y already: y=x+4.
this means you can substitute the y for (x+4). if we substitute y for (x+4) in the equation y=-5x-2, we get this:
(x+4)=-5x-2
then solve for x
6x=-6
so x=-1
since we know the x value, we can solve for y
y=x+4
y=-1+4
y=3
so the final answer is (-1, 3)
Answer:
(- 1, 3 )
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
y = - 5x - 2 → (2)
Substitute y = x + 4 into (2)
x + 4 = - 5x - 2 ( add 5x to both sides )
6x + 4 = - 2 ( subtract 4 from both sides )
6x = - 6 ( divide both sides by 6 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting into (1)
y = - 1 + 4 = 3
solution is (- 1, 3 )

Which is the equation of the line through the point (−3, 8) that is perpendicular to the line y=14x+12?
Answer:
y = -1/14x + 109/14
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 14x + 12. Its slope is 14. A line perpendicular to this one will have a slope of -1/14.
Plug this value (-1/14) into your standard point-slope equation of y = mx + b.
y = -1/14x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-3, 8). Plug in the x and y values into the x and y of the standard equation.
8 = -1/14(-3) + b
To find b, multiply the slope and the input of x (-3)
8 = 3/14 + b
Now, subtract 3/14 from both sides to isolate b.
8 - 3/14 = b
112/14 - 3/14 = b
109/14 = b
Plug this into your standard equation.
y = -1/14x + 109/14
This equation is parallel/perpendicular to your given equation (y = 14x + 12) and contains point (-3, 8)

In 2002, the membership of a club totaled 5 thousand. By 2005, there were 29 thousand members of this club.
a. Write two ordered pairs of the form (x,y), where x is years after 2002 and y is membership in thousands.
b. Assume that the membership is linear between the years 2002 and 2005. Use the ordered pairs from part (a) to write an equation in slope-intercept form of the line
relating year and membership.
c. Use the linear equation from part (b) to predict membership in 2014.
Answer:
a)
(0, 5)
(3, 29)
b) y = 8x + 5
c) 101 thousand
Step-by-step explanation:
slope m = (29-5)/(3-0) = 24/3 = 8
y-intercept = (0, b) = (0, 5)
y = mx + b
y = 8x + 5
2014 - 2002 = 12
y = 8(12) +5
y = 96 + 5 = 101
