Question

Use the line tool to graph the equation on the coordinate plane. y=−2x

Answer 1

y = mx +b

y = -2x +0

the y intercept is 0

so one point is (0,0)

the slope is -2

we go down 2 to the right 1  (1,-2)

we now have 2 points

2 points make a line

Answer 2

The slope is -2 and the it goes through origo so y = 0
