4.1 Write Linear Equations in Slope Intercept Form

Write an equation with slope = -3 and y-intercept = 5

• 3y + 5x = 15

• y = 3x + 5

• y = -3x + 5

• y = 5x - 3

How do you identify the slope in a linear equation that is in slope intercept form? y = mx + b

• the number in front of the y

• the number used for b

• the number in front of x

• you subtract x and y

What is the y intercept of the following graph?

• 0

• 1

• 3

• 4

What is the slope of the following graph? Hint  $\frac{\text{rise}}{\text{run}}=$  

• 0

•  $\frac{1}{3}$   $\text{}$  

•  $\frac{1}{2}$  

• 2

 $m=\frac{y_2-y_1}{x_2-x_1}=$ 

Write the equation of the line containing (0, 4) and (1, 7)

• y = 1/3x + 2 2/3

• y = 3x + 2 2/3

• y = 1/3x + 4

• y = 3x + 4

What is the slope in the equation:  y=4x+3

• 3

• 4x

• 4

• 3x

What is the y-intercept in the following equation:  y=-4x-5

• (-4,0)

• (0,-4)

• (0,5)

• (0,-5)

Write an equation with slope = 1 and y-intercept = 8

• y = 8

• y = x + 8

• y = 8x

• y = 8x + 1

Write equation of the line containing f(0) = 2 and f(1) = 5.

• y = 1/3x + 2 2/3

• y = 3x + 2 2/3

• y = 1/3x + 2

• y = 3x + 2

What is the equation of this line?

• y = 2x +2

• y = 2x -2

• y = -x + 2
