y = mx + b where m is the slope and b is the y-intercept
substitute what you have been given, 3/4 slope; y-intercept -35
y = 3/4 x + (-35)
Set up an x ! y chart to determine points for graph
start with 0 for x
x ! y
______
0 ! -35
4 ! -32
8 ! -29
Look for pattern
slope is y/x (y2 - y1) / (x2 - x1)
slope is 3/4
