Answer 1

you can use y=mx+b. m=slope and b=the y-intercept

Answer 2

slope = (y2 - y1) / (x2 - x1)
(3,5) x1 = 3 and y1 = 5
(-4,2) x2 = -4 and y2 = 2
now we sub
slope(m) = (2 - 5) / (-4 - 3)
slope(m) = -3/-7
slope(m) = 3/7

now we will use y = mx + b
slope(m) = 3/7
(3,5) x= 3 and y = 5
5 = 3/7(3) + b
5 = 9/7 + b
5 - 9/7 = b
35/5 - 9/7 = b
26/7 = b (for graphing purposes, 26/7 = 3 5/7)

your equation is : y = 3/7x + 26/7
