Determine the slope and y-intercept of the line 3x+4y=12. Graph the line, labeling any intercepts.
We write the equation 3x+4y=12 in slope intercept form to find the slope. We get
3x+4y=12Given equation4y=−3x+12Subtract 3xy=−34x+3Divide by 4
The slope is −34. To find the y-intercept, we let x=0 and solve for y. So we have
y=−34(0)+3x=0y=3
The y-intercept is 3.
