Im really confused! ! explain your answer, you!

ABOUT THIS FORMULA:

Y2 - Y1

        X2 - X1

FOR PROBLEM: (2, 1) & (0, -5)

Y2 is -5Y1 is 1X2 is 0X1 is 2

ABOUT POINT SLOPE FORM:

y - Y1 = m(x - X1)Y1 & X1 is a pointm represents the slopeThis form allows you to identify the slope & the point on the line

ABOUT SLOPE INTERCEPT FORM:

y = mx + bm represents the slopeb represents the y - intercept AKA the starting point

Y2 - Y1

X2 - X1

-5 - 1

0 - 2

-6

-2

SIMPLIFIED: -3 because both -6 & -2 can be divided by 2.

y - Y1 = m(x - X1)

y - -1 = -3(x - 2)

y + 1 = -3x + 6

   - 1           - 1

y = -3x - 5 --- SLOPE INTERCEPT FORM

I do not see y = -3x - 5 as one of your answer choices So, I am sorry if I am incorrect...

x=-1

x=5
