Answer:
y = 4x + 36
Step-by-step explanation:
To find the equation in slope-intercept form, rearrange to isolate "y".
Slope-intercept form is y = mx + b. The variables mean:
"x" and "y" - points that are on the line, or solutions.
"m" - the slope, how steep the line is
"b" - the y-intercept, when the line touches the y-axis
Isolate "y".
8x - 2y = -72
8x - 8x - 2y = -72 - 8x Subtract 8x from both sides.
-2y = -72 - 8x Left side : 8x - 8x = 0
[tex]\frac{-2}{-2}y = \frac{-72}{-2} - \frac{8}{-2}x[/tex] Divide both sides by -2
y = 36 - (-4)x Simplify the fractions
y = 36 + 4x Remember two negatives make a positive, add 4x.
y = 4x + 36 Put "4x" in front of 36. It looks like y = mx + b now.
"m" would be 4.
"b" would be 36.
