Graph the function

f(x)=3x+5

(remember slope intercept form f(x)=ax+b where a is slope, b is y-intercept) Start by plotting the y-intercept, then count the slope to the next point

Answer explanation

Graph the function

f(x)=3x-5

(remember slope intercept form f(x)=ax+b where a is slope, b is y-intercept) Start by plotting the y-intercept, then count the slope to the next point

Answer explanation

Don't forget slope from a graph is rise/run. What is the y-intercept? (a)  

• B

• A

• C

• D

Graph:

y= 1/3(x)-2

Match the correct statement to the graph that matches. Remember "m" is slope and "b" is y-intercept!

• Graph has positive m and a negative b.

• 
• Graph has negative m and a positive b.

• 
• Graph has positive m and a positive b.

• 
• Graph has negative m and a negative b.
