What is the point-slope form of a linear equation?

• y = x + b

• y - y1 = m(x - x1)

• y = mx

• y = mx + b

Find the equation of a line in point-slope form if the line passes through the point (4, 5) and has a slope of -3.

• y = -3x + 17

• y = 3x - 17

• y = -3x - 17

• y = 3x + 17

What is the standard form of a linear equation?

• Ax + By = D

• Ax + By = C

• Ax + By = E

• Ax + By = F

Convert the equation 2x - 3y = 6 into slope intercept form.

• 3y = -2x + 6

• 2x - 3y = 6

• y = (3/2) x - 2

• y = (2/3) x - 2

How do you find the slope of a line given two points?

• slope = (x1 - x2) / (y1 - y2)

• slope = (y2 - y1) / (x2 - x1)

• slope = (y1 - y2) / (x1 - x2)

• slope = (x2 - x1) / (y2 - y1)
