4.6 - 4.7 QUIZ

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 strategy for graphing point-slope form?

• Graph the y-intercept, then use the slope to move.

• Divide to find the x- and y-intercepts.

• Graph the given point, then move according to slope.

For the equation

y + 1 = −3(x - 5),

the line contains the point (5, −1), but what is the slope?

• −1

• 3

• −3

• 5

For the equation

y + 1 = 1/4(x - 5),

the line contains the point (5, −1), but what is the slope?

• 1

• 5

• 1/4

• −1

For the equation
y - 3 = 2(x + 4),
the line has a slope of 2 and contains what point?

• (-4, 3)
• (3, -4)
• (-3, -4)
• (-4, -3)

For the equation

y + 2 = 5(x - 4),

the line has a slope of 5 and contains what point?

• (4,−2)

• (−4,2)

• (5,0)

• (4,2)

For the equation

y + 3 = -4(x - 2),

which of the following is true?

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

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

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

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

Write the equation in point-slope form

of the line that passes through the point

(4, -7) and has a slope of -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 of the line

in Point-Slope form that goes through

the point (10,5) and has a slope of -3

• y - 5 = -3(x - 10)

• y= -3x + 35

• y + 5= -3(x + 10)

• y= -3x - 35

Convert the equation of the line

y + 5 = -3(x - 6)

into slope intercept form.

• y = -3x - 23

• y = -3x - 13

• y = -3x - 11

• y = -3x + 13
