MULTIPLE CHOICE QUESTION

2 mins • 5 pts

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

y = y1 + m(x - x1)

Ax + By = C
y = mx + b

2.

MULTIPLE SELECT QUESTION

30 sec • 5 pts

Select all of the equations which are in point-slope form.

y = 2 + 5(x - 2)

3x + 2y = 12

y + 2 = 1/4(x + 4)

y = 4x + 6

2y = 5x - 7

Answer explanation

Another form of the point-slope equation puts the y-coordinate on the other side of the equals sign with the y. So it looks like y - y1 = m(x - x1).

Write the equation in point-slope form

for the line that contains the points

(3, -5) and (5, - 1)

y = 5 + 2(x + 3)

y = -5 + 2(x - 3)

y = 3 + 2(x + 5)

y = -3 + 2(x - 5)

Answer explanation

Find the slope by subtracting the y values, divided by the subtracted x values. Then choose one of the points to plug into y = y1 + m(x - x1).

MULTIPLE CHOICE QUESTION

What is the equation in Point-Slope form

of the line that goes through

the point (6,1) and has a slope of -3?

y = 6 - 3(x - 1)

y = -6 - 3(x + 1)

y = 1 - 3(x - 6)

y = -1 - 3(x + 6)

MULTIPLE CHOICE QUESTION

5 mins • 5 pts

Convert the equation of the line

y = -5 - 3(x - 6)

into slope intercept form. (Simplify to y = mx + b)

y = -3x - 23

y = -3x - 13

y = -3x - 11

y = -3x + 13
