can paypal you if you can do these math questions and show work please.?

m = 3/4, (x1, y1) = (-4, 5)
point-slope form
(y - y1) = m(x - x1)
(y - 5) = (3/4)(x + 4)
slope-intercept
y = mx + b
still know m
b is the y value when x = 0
(y - 5) = (3/4)(0 + 4)
(y - 5) = 3
y = 8
y = (3/4)x + 8

5.
slope m is difference in y divided by difference in x
You can either do (y1 - y2)/(x1 - x2) or (y2 - y1)/(x2 - x1)
It doesn't matter
(8 - 12)/(6 - 4) = 2
(-12 - 8)/(-4 - 6) = 2
m = 2
Same as above using point-slope
(y - y1) = m(x - x1)
(y - 8) = 2(x - 6)
or
(y + 12) = 2(x + 4)

The question is for you to ponder:
