Question

What are the x and y-intercepts of the graph of 2x-4y=7 ?

A. 7/2;-7 B. -7/4 ; 7/2 C. 7/2 ; -7/4

Answer 1

the y intercept occurs when x = 0. The x intercept(s) occure when y = 0.

Answer 2

Alright, but how do I get my answer or how do I write the equation to solve it?

Answer 3

well when \(x=0\) you have\[-4y=7\]and when \(y=0\) you have\[2x=7\]

Answer 4

so solve those for x and y and you have your intercepts.

Answer 5

Oh ok thanks, That really helped.!!

Answer 6

@richyw sorry to call you back but would the correct answer be C?

Answer 7

yup, the line x=0 lies along the y axis, so you set x=0 to find the y intercept.
