Writing Equations In Slope-Intercept Form

Write an equation of a line with slope 3 and y-intercept 8.

• $y=3x+8$

• $y=8x+3$

• $3x+8y=24$

• $y=\frac{1}{3}x+8$

Write an equation of a line with slope  $-4$   and y-intercept  $0$ .

•  $y=-4$ 

•  $x=-4$ 

•  $y=-4x$ 

•  $x=0$ 

Write an equation of the line in slope-intercept form.

•  $y=\frac{1}{3}x+5$ 

•  $y=3x+5$ 

•  $y=\frac{3}{4}x+1$ 

•  $y=\frac{4}{3}x+1$ 

Write an equation of the line in slope-intercept form.

•  $y=-\frac{1}{2}x+3$ 

•  $y=-2x+3$ 

•  $y=2x+3$ 

•  $y=\frac{1}{2}x+3$ 

In 2003 a gallon of gas cost $1.75. In 2013 a gallon of gas cost $3.50. Write a linear model that represents the cost (x) as a function of the years.

• $f\left(x\right)=1.75x\ +\ 0.175$

• $f\left(x\right)=0.175x+1.75$

• $f\left(x\right)=2013x+3.50$

• $f\left(x\right)=2003x+3.50$

A canoe rental service charges a $20 transportation fee and $30 dollars an hour to rent a canoe. Write an equation representing the cost, y, of renting a canoe for x hours. 

• y = 20 + 30x
• y = 30 + 20x
• y = 50x
• y = 60x

Which equation matches the table?

• y = x + 5
• y = 5x
• y = x - 5
• x = y - 5

What does 'b" represent in
