How do you find the x and y intercept for #y=2x+3#?

Answer 1

Julia Adams

To find the #y#-intercept, set #x=0#.

#y=2(0)+3=3#.

So, the #y#-intercept is #3#.

To find the #x#-intercept, set #y=0#.

#0=2x+3#

by subtracting #2x#

#=> -2x=3#

by dividing by #-2#,

#=> x=-3/2#.

So, the #x#-intercept is #-3/2#.

To find the x-intercept, set y equal to zero and solve for x.

0 = 2x + 3

Solve for x:

2x = -3

x = -3/2

So, the x-intercept is (-3/2, 0).

To find the y-intercept, set x equal to zero and solve for y.

y = 2(0) + 3

y = 3

So, the y-intercept is (0, 3).

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.
