You first find the y-intercept which is the b, in this case 6. You also find the slope, which is the coefficient of the x. In this case, it is 3.

Explanation:

You plot the point (0,6), which is the y-intercept. Then, with the slope, you move 1 x, and move 3 y, which is 1 right and 3 up. You get that point, and connect it with the y-intercept and extend. You have a extrapolate.

"see explanation"

Explanation:

"one way is to find the x and y intercepts, that is"
"where the graph crosses the x and y axes"

• " let x = 0, in the equation for y-intercept"

• " let y = 0, in the equation for x-intercept"

y=3x+6" is the equation to be graphed"

x=0toy=0+6=6larrcolor(red)"y-intercept"

y=0to3x+6=0rArrx=-2larrcolor(red)"x-intercept"

"plot the points "(0,6)" and "(-2,0)

"and draw a straight line through them for graph"

graph{(y-3x-6)((x-0)^2+(y-6)^2-0.04)((x+2)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
