Key learning points

Gradient $m=\frac{y_2-y_1}{x_2-x_1}$ ; intercept is where the line meets the $y$ -axis.
$y=mx+c$ is the standard straight-line form.
Plot carefully: scale axes evenly and label.

Worked example 1 — Gradient

Through $(1,2)$ and $(3,8)$ . Gradient?

Working

m=3

Rise over run.

Worked example 2 — Y-intercept

$y=3x-4$ meets the $y$ -axis where?

Working

(0,-4)

Set $x=0$ .

Worked example 3 — Evaluate

For $y=2x+1$ , find $y$ when $x=3$ .

Working

y=7

Substitute.
