A line crosses the x - axis at -2. The coordinates of the x-intercept are:

• (0, -2)

• (2, -2)

• (-2, 2)

• (-2, 0)

A line crosses the y-axis at 6. The coordinates of the y-intercept are:

• (6,0)

• (6, -6)

• (0, 6)

• (-6, 6)

In the equation of a straight line graph, which statements are correct?

• m is the steepness or slope

• c is the x-intercept

• m is the gradient

• c is the y-intercept

In the line y = 2x - 3,

• the gradient is -3

• the line intercepts the y-axis at 2

• the gradient is positive

• the line intercepts the y-axis at 3

For the line represented by y = -4x

• the line slopes downwards from left to right

• the gradient is positive

• the line passes through the origin

• the value of m is -4

Select the correct answer(s)

• Two lines have a positive gradient

• The x-intercept of the orange line is (-3,0)

• The coordinates of the y-intercept of the red line is (1,0)

• the blue line passes through the origin
