What is the equation of the line with an x-intercept of -1 and a y-intercept of 2?
a) y = 2x - 2
b) y = - 2x + 2
c) y = 2x + 2

The equation of the line for this question can be stated as,

What does y = when x is -1 or

What does x = when y is 2

So since the slope of the line is 2, we can assume that B and C must be the answers but since you want one answer we need to be more accurate.

The answer is C

Because when y = 0 x = -1 and when y = 2 x = 0
