You can put this solution on YOUR website!
y=4x+3: y-intercept at (0,3)
0=4x+3: Set y=0
4x=-3
x=-3/4: x-intercept at (-3/4,0)
Let x=1
y=4(1)+3
y=4+3
y=7 : Checkpoint at (1,7)
+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+4x%2B3%29+
The graph crosses the y axis at3, the x axis at -3/4 and includes the point (1,7)
