Question

Write the equation in slope-intercept form. (-7,-2), (2,3)

Answer 1

Answer:

y = -5/9x + 4.1

(try doing this yourself first with different points to make sure this is the right answer, because im to lazy to check myself but ill try checking D:)

Step-by-step explanation:

first you have to find the slope . to do this use the equation y2 - y1/ x2 - x1

so write as -2 - 3/  -7 - 2 is equal to -5/-9

so now write y = -5/9x + b

we must now find the y-intercept so substitute one of the points given. lets substitute 2,3 it looks easier. So it will look like 3 = -5/9(2) + b

3 = -5/9(2) + b

3 = -10/9 + b

b = 3 + 10/9

b = 4.111111

um just round to the tenth place
