What is the equation of a slope of -3 and a 4- intercept of -8

If it says "what is the equation of a slope of -3 and a y-intercept of -8"

Slope-intercept form:  y = mx + b

("m" is the slope, "b" is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis]

Since you know:

m = -3

b = -8                Substitute/plug it into the equation

y = mx + b

y = -3x - 8

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
