Answer:

When <u>graphing inequalities</u>:

< or > : draw a dashed line

≤ or ≥ : draw a solid line

< or ≤ : shade under the line

> or ≥ : shade above the line

<u>Question 14</u>

Given inequalities:

y \geq x - 3

y > -4x + 2

Treat the inequalities as equations (swap the inequality sign for an equals sign) to find two points on the line to help draw the lines.

y \geq x - 3

x=0 \implies y=-3

x=3 \implies y=0

Plot the points (0, -3) and (3, 0).

Draw a <u>solid straight line</u> through the points.

y > -4x + 2

x=0 \implies y=2

x=1 \implies y=-2

Plot the points (0, 2) and (1, -2)

Draw a <u>dashed straight line</u> through the points.

Shade the intersecting area <u>above</u> the two lines.

<u>Question 15</u>

Given inequalities:

y \geq -3x - 3

y \geq -\dfrac{1}{2}x + 2

Treat the inequalities as equations (swap the inequality sign for an equals sign) to find two points on the line to help draw the lines.

y \geq -3x - 3

x=0 \implies y=-3

x=-2 \implies y=3

Plot the points (0, -3) and (-2, 3).

Draw a <u>solid straight line</u> through the points.

y \geq -\dfrac{1}{2}x + 2

x=0 \implies y=2

x=2 \implies y=1

 Plot the points (0, 2) and (2, 1)

Draw a <u>solid straight line</u> through the points.

Shade the intersecting area <u>above</u> the two lines.
