Writing Equations in Slope-Intercept Form

What is the slope-intercept form of a linear equation?

• y = mx^2 + b

• y = m/x + b

• y = ax^2 + bx + c

• y = mx + b

If the slope is -3 and the y-intercept is 1/2, what is the equation of the line?

• y = 3x + 1/2

• y = -3x - 1/2

• y = 3x - 1/2

• y = -3x + 1/2

How do you find the slope from a graph?

• By counting the vertical and horizontal units between two points

• By calculating the area under the line

• By measuring the angle of the line

• By finding the midpoint of the line

How do you write a linear function in function notation?

• f(x) = mx + b

• y = mx + b
