Basic Slope Intercept

What letter represents the slope of a line in the equation y = mx + b?

• y

• m

• x

• b

Find the slope of the line.

• 1/2

• -1/2

• 2

• -2

Write the equation of the line.

• y = -1/3x - 2

• y = 1/3x - 2

• y = 3x - 2

• y = -3x - 2

Which of these represents slope-intercept form?

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b

If m=3 and b=6, what is the correct slope intercept equation?

• y=3-6

• y=3x-6

• y=3x+6

• y=6x+3

How would you write the equation with a slope of -3 and a y-intercept of 1

• y= -3x + 1

• y= -x - 3

• y= -3x - 1

• y= x + 3

How would you write the equation with a slope of 4/5 and a y-intercept of -1

• y= -x + 4/5

• y= x + 4/5

• y= 4/5x - 1

• y= 2/5x + 4/5

What is the y-intercept of the line graphed below?

• 3

• 4/3

Write the equation for the line in slope-intercept form.

• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3

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

• 6
