2. a line passes through (1, -5) and (-3, 7).
a. write an equation for the line in point-slope form.
b. rewrite the equation in slope-intercept form.

a y - 5 = 3(x + 1); y = 3x + 8
.
d y + 5 = -3(x - 1); y = -3x - 2

The answer would be d) y + 5 = -3(x - 1); y = -3x - 2
The answer is d because you would find the slope by doing y2 - y1 / x2 - x1 ( 7 + 5 / -3 - 1 ) which equals -3. You would use your first coordinate and the slope -3 then plug that into the point slope formula ( y + 5 = -3(x - 1) ). If you simplify that equation you would get y = -3x - 2

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
