Question

the slope of the line is 2 and the x-intercept is -3, which line is it?

Answer 1

slope intercept formula is y = mx + b
where m is slope always with x
and b is y-intercept
and they gave you x = -3 which mean y = 0
so plug all these value into the equation and then solve for b

Answer 2

replace these by their value and then solve for b
