The x-intercept is when y=0 so substitute y=0 into the given equation and solve for x:
2x+3y=−9
2x+3(0)=−9
2x=−9
x=−4.5
Given equation. Substitute y=0. Simplify. Divide both sides by 2.
The x-intercept is then x=−4.5
The y-intercept is when x=0 so substitute x=0 into the given equation and solve for y:
2x+3y=-9
2(0)+3y=-9
3y=-9
y=-3
The y-intercept is then y=−3.
Plot the xx-intercept at −4.5 and the y-intercept at −3. Then draw a line passing through the intercepts to graph the line:
