12 questions

Question 1

The formula for finding the slope of a line is:

Rate of change = change in y/change in x

Run/Rise

m = x -x/y - y

Rise/Run

m  = y- y/x - x

m = y/x

Question 2

Find the slope given the following 2 points (14, -8) & (7, -6).

Question 3

Identify which statements are true about Standard Form.

A    "A & B" can't be negative

B    "A" can't be a fraction

C   "A" can't be negative; "B" can be negative

D   "A" is always paired up with the variable "y"

E   "B" can't be a fraction

F   "C" can't be negative

G  "C" can be positive or negative

H  "B" is always paired up with the variable "y"

Question 4

Rate of Change and Slope are universal terms. (same thing)

True

False

Question 5

Write the equation that represent Standard Form.

Question 6

Determine if 4x = 8y - 5 is written in Standard Form. If not, write it in Standard form.

Question 7

Draw a graph and graph the x- and y- intercept of (-3,0) and (0,2). Don't forget to connect the points on the graph with a line.

Question 8

What is the formula for slope-intercept form?

Question 9

Identify the y-intercept of the linear equation y = -4/5x - 6.

Question 10

10.

Given 6x - 4y = -12, which equation below has been correctly written in slope-intercept form?

4y = -6x - 12

6x = -4y - 12

x = -2/3y -2

y = -3/2x - 3

6x - 4y = -12

y = -3/2x + 2

Question 11

11.

Draw the slope of a line with a negative slope.

Question 12

12.

Which line(s) has a negative slope?

y = x + 4

y = x - 1

2y + 3x = 6
