Y - 1 = 6(x - 1)

Please help me and explain :)

y=6x-5

Step-by-step explanation:

y-1=6(x-1)  

(distribute 6 to x-1)

y-1=6x-6

(add 1 to both sides)

y=6x-5

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
