Jayden measured a desk to be 4 feet. The actual measure is 3.2 feet. What is jayden’s percent error? A: 20%
B: 25%
C: 30%
D: 35%

B: 25%

Step-by-step explanation: 4/3.2 is 1.25, move the decimal over, and round down. 0.25

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
