Answer:

Explanation:

y=mx+b where m is the slope and b is the y intercept, value of y when x=0

11.

Since we are given the point (0,4) we already know that b=4

slope is m=(y2-y1)/(x2-x1), using our two points (0,4)(-1,3) we have

m=(3-4)/(-1-0)

m=-1/-1=1 so the line is

y=x+4

12.

Again they gave us point (0,1) so we know b=1, from points (0,1)(4,2) we find

m=(2-1)/(4-0)

m=1/4 so our line is

y=x/4+1 (or more neatly)

y=(x+4)/4
