Why might a person use a point-slope formula?

• The graph's has no slope

• The graph's line does not cross the y-intercept

• The graph's line does not cross the y-intercept at a whole number (easy to work with)

• The graph does not any a (x, y) points

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)

Write the equation in point-slope form of the line that passes through the given point and has the given slope. (-1, 2); m = 7

• y + 1 = 7(x - 2)

• y - 2 = 7(x + 1)

• y+ 1 = 2(x + 7)

• y - 2 = 7(x - 1)

What is the slope in the following equation?
y-1 = 4(x+2)

• 2

• -1

• 4

• -2

Write the equation in point-slope form of the line that passes through the given point and has the given slope. (2, 5); m = -3

• y +3 = 5(x - 2)

• y - 5 = -3(x - 2)

• y+ 5 = -3(x +2)

• y - 2 = 5(x - 3)

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

• y - 7 = -1/4(x - 4)

Write the equation of a line parallel to the one pictured through the point (3,1) in point slope form.
(HINT: PARALLEL LINES HAVE THE SAME SLOPE)

• y - 1 = 1/2(x - 3)

• y + 1 = 1/2(x + 3)

• y - 1 = - 1/2(x - 1)

• y + 1 = - 1/2(x + 3)

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

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b

• y=kx
