Question

if I am trying to find the x and y intercept, how would I with "y=x-5"

Answer 1

to find the y-intercept, replace x with 0 and evaluate

what do you get?

Answer 2

y=-5

Answer 3

the y-intercept is (0,-5) which means there is a point at -5 on the y axis where the graph goes through

Answer 4

now plug in y = 0 and solve for x. This will give you the x-intercept

Answer 5

what formula do I use?

Answer 6

y = x-5

0 = x-5 ... replace y with 0

now isolate x. To do so, you add 5 to both sides (to undo the subtraction of 5)

Answer 7

so 5 = x?

Answer 8

yep x = 5 which means the x-intercept is (5,0)

basically 5 on the x axis
