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

Pitanje 2

2.

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

Pitanje 3

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"

5.

Write the equation that represent Standard Form.

Pitanje 6

6.

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

Pitanje 7

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.

Pitanje 8

8.

What is the formula for slope-intercept form?

Pitanje 9

9.

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

Pitanje 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

Pitanje 11

11.

Draw the slope of a line with a negative slope.

Pitanje 12

12.

Which line(s) has a negative slope?

y = x + 4

y = x - 1

2y + 3x = 6
