Writing Linear Equations

Which of these represents point-slope form of a linear equation?

• y - y₁ = m(x - x₁)
• Ax + By = C
• y = mx + b

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y +7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y+ 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)

What two things do you NEED to write an equation in point-slope form?

• a slope and a y-intercept

• a slope and a x-intercept

• a slope and a point

• two points on the line

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)
• y + 1 = -3(x + 2)
• y - 1 = 3(x - 1)
• y + 2 = -3(x + 1)

Which of the following is the equation of the line in SLOPE INTERCEPT FORM that has a slope of 3 and passes through the point (0, 9)?

• y = -3x + 12

• y = 3(x + 9)

• y = 3x + 9

• y = 3x - 3

If a line passes through (0,6) and has a slope of 2, what is the equation for the line written in slope intercept form?

• y = 2x

• y = 2x + 6

• y = 6x + 2

• y = 2x - 6

• y = x + 8

• y = -x + 8

• y = 2x + 8

• y = 2x + 6
