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

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

What is the point given in this equation?

y-3=7(x+1)

• (3,1)

• (-3,1)

• (-1,3)

• (1,-3)

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.
(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)
