What is the equation of the line that has a slope of -2 and a y-intercept of -7?

y = -2x - 7
y = -7x - 2 <-
y = -2x + 7
y = -7x + 2

Find the equation of the line that has a slope of 4 and contains the point (-4, 1).

y = 4x + 1
y = 4x - 8
y = 4x - 15 <--
y = 4x + 17

Find the equation of the line that passes through the point (1,5) and has a slope of -2.

y = -2x + 7 <-- im not sure
y = -2x + 11
y = 2x - 9 or <--
y = 2x + 3

Which equation represents the line that passes through the points (-3,7) and (3,3)?

y=2/3x+1
y=2/3x+9 <-- im not sure on the last two.
y=-2/3x+9
y=-2/3x+5

nope, all wrong. Let me give you a link to solving these. Take a few minutes and watch this:
https://www.khanacademy.org/math/algebra/two-var-linear-equations/writing-slope-intercept-equations/v/linear-equations-in-slope-intercept-form
Then on the left, if you wish, there are some practice problems.
Make sure you go thru the entire video, you need to understand this....and it is not hard.
