x equals 1

step-by-step explanation:

f(4)=f(×)

x=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

do it yourself this is easy

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3
