Question

What is the equation in slope intercept form of the line that contains the point (8, -2) and has a y-intercept of -4?

Answer 1

y=mx+b,slop intercept form
we need to find the slope.we nned to point
(-8,2) is given you can get the other by understanding the defintion of y-intercept (0,-4)
$m = slope = \frac{ 2 - ( - 4)}{ - 8 - 0} = \frac{6}{ - 8}$
m=-6/8,b=y-intercept=-4
$y = \frac{ - 6}{8} x + ( - 4)$
