Question

Solve as y=mx+b
Write an equation of the line below.

Answer 1

Answer:

y = 2x

Step-by-step explanation:

Since the line passes through the origin or (0,0), adding + 0 is irrelevant so we are just looking for slope.

Since there is a rise of 2 units every one unit, the slope or m = 2.

Since we know two points by observing the graph (0,0) and (3,6). m = y2-y1/x2-x1 = 6-0/3-0 = 6/3 = 2/1 = 2
