Use Point Slope Form to find the equation of the line through the point with the given slope.

m= 5

(2, 4)

• y - 2= 5(x - 4)

• y - 4= 5(x - 2)

• y- 5 = 4(x - 2)

• y - 2 = 4(x - 5)

Use Point Slope Form to find the equation of the line through the point with the given slope.

m=4

(2, 2)

• y- 2 = 4( x - 2)

• y- 4=4(x - 2)

• y- 2= 2( x - 2)

• y + 2 = 4(x + 2)

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)

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)

The line with the equation

y + 1 = -3(x - 5),

contains the point (5, -1)

and has a slope of _______.

• -1

• 1

• -3

• 5

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 slope-intercept form for the line that contains the points
(3, -5) and (5, - 1)

• y = 2x + 11
• y = 2x + 1
• y = 2x - 1
• y = 2x - 11

Find the slope of the line that goes through the points

(−11,−5) and (1,−12)
