y=x+1

Step-by-step explanation:

Slope, 1x

Y intercept, 1

y=x+1

x= y-1

Step-by-step explanation:

For example if x is 4 on the graph, y is 5 or if x is 0 then y is 1

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
