Answer:

Explanation:

The equation for the slope of a line is


(y2-y1)/(x2-x1)

in this case

y2 = -4 and y1 = 2

x2 = 4 and x1 = 1

so -
(6)/(3) is the slope

this can be simplified as -2

-2 = m

b can be found simply by observing where the line crosses the y axis or where x = 0

so

y = -2x + 4
