You can put this solution on YOUR website!
x=0 y=6
x=1 y=4.5
x=2 y=3
x=3 y=1.5
x=4 y=0
Use any two points to find the slope of the line:
(0, 6) and (1, 4.5)
Slope = -1.5
.
y=mx+b [Use the slope-intercept equation of a line]
6=(-1.5)(0)+b [Plug-in any point plus the slope and solve for b]
6=b
.
y=mx+b [Plug-in the value for the slope and the y-intercept]
y=-1.5x+6 [The slope-intercept equation of a line]
