3x-8y=42 Start with the given equation.


-8y=42-3x Subtract 3x from both sides.


-8y=-3x%2B42 Rearrange the terms.


y=%28-3x%2B42%29%2F%28-8%29 Divide both sides by -8 to isolate y.


y=%28%28-3%29%2F%28-8%29%29x%2B%2842%29%2F%28-8%29 Break up the fraction.


y=%283%2F8%29x-21%2F4 Reduce.


So the equation y=%283%2F8%29x-21%2F4 is now in slope intercept form y=mx%2Bb where the slope is m=3%2F8 and the y-intercept is b=-21%2F4 note: the y-intercept is the point

We are given
3x-8y=42
Solve for y by -3x from both sides as
-8y = -3x + 42
Divide by -8 to get
y = (3/8)x - 21/4
slope,m, is (3/8)
Y-intercept, b, is -21/4.

what is the slope and y-intercept of the line 3x-8y=42
---------------------------------
Solve for "y":
8y = 3x-42
y = (3/8)x - (21/4)
--------------------------
slope = 3/8
y-intercept: -21/4
