How do you find the x and y intercept given #y = 7/8x + 10#?

Answer 1

To find the y-intercept, substitute #0# for #x#: #y =7/8(0)+10# #y=10# The y-intercept is #10#.

To find the x-intercept, substitute #0# for #y#: #0=7/8x +10# #7/8x =-10# #x =-10*8/7# #x = -80/7# The x-intercept is #-80/7#.

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

For the x-intercept: 0 = 7/8x + 10 -10 = 7/8x x = -10 * 8/7 x = -80/7

For the y-intercept: y = 7/8(0) + 10 y = 10

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.
