Can somone plz show me how to get the answer?? plz

8. y = -3x - 4

9. y = -5

Step-by-step explanation:

8. The points are (-3, 5) and (0, -4)

                            (x1, y1)       (x2, y2)

The gradient formula is (y2 - y1)/(x2 - x1)

(-4 - 5)/(0 - (-3))

-9/3

m (gradient) = -3

y = -3x + c

c is the y - intercept and it is given that when x is 0, y = -4 (this is our y-intercept)

Hence: y = -3x - 4

9. It doesn't have a slope, meaning the line is going horizontally. If it is going horizontally then it would be on the y-axis. Hence y = -5

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
