How do you graph using the intercepts for #2x+y=19#?

Answer 1

Savannah Anderson

Plot the #x# and #y# intercepts on a number plane and draw a straight line through them.

The #x#-intercept can be found by subbing in #y=0#.

When #y=0#, #2x=19=>x=9.5#

The #y#-intercept can be found by subbing in #x=0#.

When #x=0#, #y=19#

To graph the equation 2x + y = 19 using intercepts, follow these steps:

x-intercept: To find the x-intercept, set y = 0 and solve for x. 2x + 0 = 19 2x = 19 x = 19/2 x = 9.5
y-intercept: To find the y-intercept, set x = 0 and solve for y. 2(0) + y = 19 y = 19

Plot these intercepts on a graph and draw a line passing through both points.

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.
