How do you find the x and y intercepts for #2x+y=9#?

Answer 1

X-intercept = #9/2# and y-intercept = 9

Since the line representing the given equation passes through x = 0 and y = 0. When x = 0, 2X0 +y = 9 y = 9 Hence y -intercept = 9 When y = 0 2x + 0 9 2x = 9 #2x/2# = #9/2# #x# = #9/2# Hence x-intercept = #9/2#

To find the x-intercept, set y to 0 and solve for x. To find the y-intercept, set x to 0 and solve for y.

For the x-intercept: 2x + y = 9 2x + 0 = 9 2x = 9 x = 9/2 x = 4.5

For the y-intercept: 2x + y = 9 2(0) + y = 9 y = 9

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.
