Question

The y-intercept of the line whose equation is x - y = 7 is A.) 7 B.) 1 C.) -7

Answer 1

C) -7

Explanation: If you rearrange the equation into slope-intercept form, you get y = x - 7 so -7 is the b value (y intercept)

Answer 2

C.) -7 is the right answer.

Explanation:

Given is an equation of a line

`x-y =7`

Write in slope intercept form as

`y =x-7`

This is of the form

`y = mx+b\\m=1\\b=-7`

y intercept = b=-7

Hence option C is the right answer.
