Write the equation of the line in slope intercept form. (-5,-7); m=-2

(-4,2); m=2

(-5,-7); m=-2   :    y = -2x - 17 (-4,2); m=2     :     y = 2x + 10

Step-by-step explanation:

Since we only have a point and the slope. Then we can write the equations in point-slope form [(y - y₁) = m(x - x₁)], the convert to slope-intercept form ( y = mx + c ).

For (-5,-7); m = -2:

Write the equation in point-slope form

  y - (-7) =  - 2 (x - (-5))  

   y + 7 =  -2 ( x + 5 )

Transpose to determine slope-intercept form

      since y + 7 =  -2 ( x + 5 )

                      y = -2 x - 10 - 7

                      y = -2x - 17For (-4,2); m=2 :

Write the equation in point-slope form

  (y - 2) =  2 (x - (-4))  

   y - 2 =  2 ( x + 4 )

Transpose to determine slope-intercept form

      since  y - 2 =  2 ( x + 4 )

                      y = 2 x + 8 + 2

                      y = 2x + 10

                   

The answer would be choice b

32

step-by-step explanation:

these are your clues: 1. kim ran 18 races2. this was four fewer races than twice thenumber, notice it says twice the number, so you would do the equation 18x2-4; which equals the number 32.thus, 32 is your answer.
