Quiz about Linear Equations

Question 1

What is the change of rate in the table?

Accepted Answer

m = .75

Answer

m = -.75

Answer

m = 7.5

Answer

m = 2.25

Question 2

Given the point-slope form equation y - 6 = $$\frac{3}{2}$$ (x - 2),

what is the equivalent equation in slope-intercept form?

Accepted Answer

y = $$\frac{3}{2}$$ x + 3

Answer

y = $$\frac{2}{3}$$ x + 2

Answer

y = $$-\frac{3}{2}$$ x + 3

Answer

y = $$-\frac{2}{3}$$ x - 3

Question 3

What is the equation of a line, in point-slope form that

passes through the point (3, 2) with slope of $$\frac{1}{4}$$ ?

Accepted Answer

y - 2 = $$\frac{1}{4}$$ (x - 3)

Answer

y + 2 = $$\frac{1}{4}$$ (x + 3)

Answer

y + 2 = - $$\frac{1}{4}$$ (x + 3)

Answer

y - 2 = $$\frac{4}{1}$$ (x - 3)

Question 4

In this graph, what is the slope of the line?

Accepted Answer

Answer

- $$\frac{1}{2}$$

Answer

-2

Answer

2

Question 5

Convert the point-slope equation y - 12 = 3(x - 9),

to Slope intercept form.

Accepted Answer

y = 3 x - 15

Answer

y = 3x -9

Answer

3x - 12y = -27

Answer

y = 3

Question 6

What is the equation of a line that contains the points (0, -3) and (6, 15)?

(chose 2)

Accepted Answer

y = 3x -3

Accepted Answer

6x + 12y = 0

Answer

y = -3x + 3

Answer

y - 15 = 3(x - 6)
