• y-intercept
• slope
• macaroni
• nothing

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

• 3
• 4x
• 4
• x

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

How would you write the equation with a slope of 2/3 and a y-intercept of -3

• y=3/2x+3
• y=2/3-3
• y=2/3x-3
• y=2/3x+3

What is 'b' in this linear equation? y= 5x - 6

• 6

• 5

• y

• -6

What is your slope and y-intercept of this equation? y= 2/3 x + 12

• m= 3/2 b= 12

• m= 12 b= 2/3

• m= 2/3 b= 12

y = -x - 3

SLOPE is

• 3

• 1

• -1

• -3

Answer explanation

Slope is always a coefficient of x.

y = -x - 3

Y-intercept is

• 3

• 1

• -1

• -3

Answer explanation

Y-intercept is always a constant.

y = -4x - 3

SLOPE is

• 3

• $\frac{4}{1}$

• $\frac{4}{-1}$
  

• -3

Answer explanation

Slope is always a coefficient of x.

 $y\ =\ x\ -\ \frac{3}{4}$
