CAN ANYONE MAKE SURE THESE ARE RIGHT?

Find the equation of the line for each situation.
A line with a y - intercept of 4 and a slope of -1
Y=-1x+4
A line passing through the point (3, 4) and having a slope of -2
Y=-2x+3
A line passing through the points (1, -1) and (9, 3)
Y=1x+9

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
