Practice Writing Equations

Write the equation of the line through the points (7, 8) and (-12, -11).

• y = x + 1

• y = x + 15

• y = -x - 1

• y = -x - 23

Write the equation of a line PARALLEL to y = 2x + 3 that passes through the point (3, 1).

Write the equation of a line PERPENDICULAR to y = -2x + 1 that passes through the point (2, 3).

Write an equation for a line PARALLEL to the line

y = 1/3x - 4 and passing through the point (-3, 2).

• y = 1/3x - 3

• y = -1/3x + 3

• y = 1/3x + 3

• y = -5/3x + 3

What is the slope in the equation:  y=4x+3

• 3

• 4x

• 4

• 3x
