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

Graph:

y= -1/2(x) +3

Graph:

y= 1/3(x)-2

• 5

• - 6

• -1.5

• + 6

• - 12

• + 12

• 2/3

• -2/3
