On Alex's map, 0.5 inch represents 20 miles. Which equation can be used to find the number of miles, m, represented by n inches?
A
m = = 0.5 (20n)

idk

step-by-step explanation:

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

(1,-1) i hope this
