8W review for exam

What are the coordinates of point K?

• (0, 3)

• (0, -3)

• (3, 0)

• (-3, 0)

The equation for a straight line is generally in the form:

• y = mx + c

• y = m + xc

• m = yx + c

• m = yx

In the straight-line equation, m refers to the:

• y-intercept

• gradient or slope of the line

• x-intercept

• origin

In the straight-line equation, 'c' (or 'b') refers to the:

• y-intercept

• gradient or slope of the line

• x-intercept

• origin

The gradient of the diagonal line (red) line is:

• positive

• negative

• zero

• undefine
