Can someone help me with these questions I don’t know how to do them

It says you have to measure the longest side of each right triangle with a ruler

measure the longest side and use a^2 + b^2 = c^2

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

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
