Question

1. What is the constant of proportionality or "m" in the equation below?

2. What is the y-intercept or "b" in the equation below?
y = -3x + 2

Answer 1

1. m = -3

2. b = 2

Explanation:

Using slope-form equation, y = mx+b where m is the gradient of the line and b is the y-intercept. So in the equation, y = -3x + 2, m is -3 and b is 2.

Answer 2

The constant of proportionality, o slope, is the coefficient multiplying
`x` in the equation. The y-intercept is the constant term added at the end, with no variable:

`y=mx+b`
