Question

Graph a line representing the proportional relationship with slope 3 containing the point (2, 6).

To graph the line, plot two points on the line.

Answer 1

(1, 3) and (0, 0)

Explanation:

y = mx + b

m is the slope which is 3 (given)

b is the y intercept

(x, y) → (2, 6)

6 = 3(2) + b

6 = 6 + b

b = 0

so the equation is y = 3x

one point:

y = 3(1)

y = 3 when x = 1

(1, 3)

y = 3(0)

y = 0 when x = 0

(0, 0)
