Answer 1

Answer:

I am pretty sure B is correct answer

Answer 2

Answer:

A. Slope is -5. Y-intercept is (0,7)

Step-by-step explanation:

1. Find the slope using the slope formula and the coordinates

Remember, the slope formula is: y2-y1/x2-x1

You'll use the coordinates (0,7) (4, -13) to plug into the formula.

-13-7/4-0

= -20/4

= -5

Slope is -5

2. Find the y-intercept.

First, write the equation of the line in point-slope form: y-y1=m(x-x1)

M is slope and y1 and x1 can be from any ordered pair (as long as they're from the same one). Let's use (0,7)

y-7=-5(x-0)

Simplify the equation.

y-7=-5x+0

y=-5x+7

3. Now the equation is in y-intercept form, or y=mx+b. Again, M is slope. B is the y intercept. So, the y-intercept is 7

Solve for r.
-13 = r/9 + 8

r = ???

Answers

Answer:

r= -189

Step-by-step explanation:

Answer:

r= -189

Step-by-step explanation:

You subract the 8 both sides:   -13= r/9+8

Which equals to: -21= r/9

In order to get the 9 off, you have to cancel it by multiplying ( opposite of   is multiplying) both sides:

9(-21)= r

And the final answer is:  r= -189

You can check it by plugging in -189 to r and it works:)

Find the rate of change (slope) from the table below

Answers

1/2 is correct.

the slope is 3/6 which is equivalent to 1/2
The slope is equivalent to -1/2. Every time the left column adds one number, the right column subtracts two. You can test this by adding in filler numbers missing in between the table. For example, between 5 and 7 would be 6. If you were subtract 2 from 10 (the previous left column answer), you would get 8. Subtract 2 from there and you would get 6. You could also test this by graphing it and simply counting how many units you’re going up or down compared to how many units you’re going left or right. Hope this helps. Lmk if you have any questions!
