Finding Line Equations from Points

What is the equation of a line that passes through the point (2, 3) with a gradient of 4?

• y = 2x + 3

• y = 3x - 2

• y = 4x + 1

• y = 4x - 5

If a line has a gradient of -2 and passes through the point (1, 5), what is its equation?

• y = -2x + 7

• y = -2x + 5

• y = 2x + 3

• y = x - 2

Find the line equation for a line that passes through (0, 0) with a gradient of 1.

• y = -x

• y = 2x

• y = x

• y = x + 1

If a line has a gradient of 0 and passes through the point (4, 6), what is the equation of the line?

• y = 4

• y = x + 6

• y = 6

• y = 0

If a line passes through the point (2, 2) and has a gradient of 1/2, what is its equation?

• y = (1/2)x + 2

• y = (1/2)x - 1

• y = 2x + 2

• y = (1/2)x + 1
