5.1-5.3 Review

In the equation y=mx+b, what does the m represent?

• slope
• y-intercept
• linear
• point-slope

What does 'b" represent in y=mx+b

• y-intercept
• macaroni
• nothing
• slope

Determine the slope and y-intercept from the following equation:   y = 3/2x + 3

• slope: 5   y-intercept:  (0,3) 
• slope: 3/2   y-intercept:  (0,3) 
• slope:  4  y-intercept:  (0,3/2)
• slope: 1/5   y-intercept:  (0,5) 

Which of these represents slope-intercept form?

• y - y₁ = m(x-x₁)
• Ax + By = C
• y = mx + b

Write the equation of the line.

• y= -1x-3
• y= -3x-1
• y=-1/3x-1
• y= -3x-3

If a line passes through (0,6) and has a slope of 2, what is the equation for the line?

• y = 2x

• y = 2x + 6

• y = 6x + 2

• y = 2x - 6

If a line passes through (0,-5) and has a slope of -8, what is the equation for the line?

• y = -5x - 8

• y = -8x + 5

• y = -8x - 5

• y = -8x

Identify the slope and the y-intercept of the graph of the following equation:

 $y=3x+5$  

• m = 3  and  b = 5

• m = 5  and  b = 3

• m = 3x  and  b = y

• There is no y-intercept.

Write the equation of the line in​ slope-intercept form using the given slope (m) and​ y-intercept (b):   

 $slope=-\frac{3}{4}$ 
 $y-intercept=-11$  

•  $y=-\frac{3}{4}x-11$  

•  $y=-11x-\frac{3}{4}$  

•  $y=-\frac{3}{11}x\ +4$  

•  $y=\frac{3}{4}x+11$  

Write the equation of the line in​ slope-intercept form using the given slope and​ y-intercept:  

 $slope=-4$  
 $y-intercept=0$  

•  $y=4$  

•  $y=-4x$  

•  $y=0$  

•  $y=-4x+4$
