Algebra 1 EOC Review - PointSlope and Par/Perp A3(B)(E)(F)

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

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

m=1/2 (-2 , 1)

y- _____ = _____ (x- _____)

Write the equation of a line with slope m = 3 that goes through the point (1,-5)

in point - slope form

Answer explanation

To write the equation, plug in the point and slope!

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)

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)

For the equation
y - 3 = 2(x + 4),
which of the following is true?

• The line has m = 2 passing through the point (4, -3)
• The line has m = 2 passing through the point (3, -4)
• The line has m = 2 passing through the point (-4, 3)
• The line has m = 2 passing through the point (-3, 4)

For the equation  y - 4 = -1/3(x - 7),  what is the point that the line passes through?

• (4, 7)
• (-7, - 4)
• (7, 4)
• (-4, -7)

Which of the following is slope intercept form?

• Ax+By = C

• y-y₁=m(x-x₁)

• y=mx+b

• I don't know
