Which of the following has a slope of 2 and a y-intercept of 4?

y = 2x + 4

y = 2x + 4

y = 2x 4

y = 2x 4

im assuming the ones that have no sign are subtraction, it just doesn't show :)
but you have two of the same!

lukecrayonz · Answer

But the answer is y=2x+4, as y=mx+b, m = slope, b = y intercept :)

Which of the following has a slope of 2 and a y-intercept of -4?
(Points : 4) 
       y = 2x + 4


       y = 2x + 4

       y = 2x  -4

       y = -2x - 4

t hat why im asking

lukecrayonz · Answer

Well no, look at the formula y=mx+b, the formula for a line. in that formula, m is your slope, b is your y intercept. So a slope of 2, y=2x so far, and your y intercept of -4, y=2x-4! :)
