A y-intercept of 8 means that
x=0 and y=8, so it is the point
(0,8)
Using point-slope formula:
+%28y+-+8%29+%2F+%28x+-+0%29+=+-3+
+y+-+8+=+-3x+
+y+=+-3x+%2B+8+Here's the plot:
+graph%28+400%2C+400%2C+-2%2C+8%2C+-8%2C+12%2C+-3x+%2B+8+%29+

Write an equation in slope-intercept form of the line with slope -3 and y-intercept 8
-----------------
These are all the same.
y = mx + b
m = slope, b = y-intercept
--------
y = -3x + 8
