• $$\frac{4}{3}$$  

• $$\frac{3}{4}$$  

• $$\frac{-4}{3}$$  

• $$\frac{-3}{4}$$  

​Identify the slope of the line

Multiple Choice

Given 2 points such as (7,3) and (4,-1). What is the slope?

$$m=\frac{y_2-y_1}{x_2-x_1}$$

​Slope - Intercept Form

Multiple Select

What is the slope and y - intercept of the equation?

$$y=3x-5$$  

• m = 3

• m = -3

• b = -5

• b = 5

​Identify the slope (m) and y - intercept (b)

Multiple Choice

Transform the equation into slope - intercept form

3x - y = 7

• y = 3x - 7

• y = 3x + 7

• y = -3x - 7

• y = -3x + 7

​Trans from the equation into slope - intercept form

​

3x - y = 7​

Multiple Choice

Transform the equation into slope - intercept from

2x + 5y = 30

• $$y=\frac{-2x}{5}+6$$  

• $$y=\frac{2x}{5}+6$$  

• $$y=\frac{-2x}{5}-6$$  

• $$y=\frac{2x}{3}+6$$  

​2x + 5y = 30

Multiple Choice

Using the equation 2x + 5y = 30, what is the slope?

• $$m=\frac{-2}{5}$$  

• $$m=\frac{2}{5}$$  

• $$m=\frac{5}{2}$$  

• $$m=\frac{-5}{2}$$  

Multiple Choice

Using the equation 2x + 5y = 30, what is the y - intercept?

• $$b=6$$  

• $$b=-6$$  

• $$b=\frac{1}{6}$$  

• $$b=\frac{-1}{6}$$  

​2x + 5y = 30
