You can put this solution on YOUR website!
Start with the y intercept, then use the definition of slope to determine anoth er point on the line. Plot those two points and connect them with a line.
(0,4)
Slope is change in y over change in x.
(0+1,4+2)
(1,6) is another point on the line.

Find the x and y intercepts of the line.
Plot them and connect them with a line.

I prefer the second, it's quicker.
X-intercept:
y=2x%2B4
0=2x%2B4
2x=-4
x=-2
(-2,0)
.

Y-intercept:
y=2x%2B4
y=2%280%29%2B4
y=4
(0,4)
