How do you graph using the intercepts for #-18x + 3y = -12#?

Answer 1

Eli Assouline

Solve for the intercepts, then draw a straight line between them.

Solving for the intercepts yields:

#-18(0)+3y=-12# #y=-4#

#-18x+3(0)=-12# #x=2/3#

So plot the points #(0,-4)# and #(2/3,0)# and draw a straight line connecting them.

To graph using intercepts for the equation -18x + 3y = -12, first find the x-intercept by setting y = 0 and solving for x. Then find the y-intercept by setting x = 0 and solving for y. Once you have both intercepts, plot them on the coordinate plane and draw a line passing through both points to complete the graph.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
