Slope-Intercept Form: Graph Interpretation Challenge

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

• y = mx + b

• y = ax^2 + bx + c

• y = mx - b

• y = m + bx

If a line crosses the y-axis at 1, what is the y-intercept?

• -1

• 1

• 0

• 2

How do you find the slope from a graph?

• Calculate the area under the line

• Find the x-intercept

• Measure the angle of the line

• Count the rise and run between two points

If a line rises 6 units and runs -3 units, what is the slope?

• -2

• 2

• 1/2

• -1/2

What is the equation of a line with a y-intercept of -3 and a slope of 1/3?

• y = 1/3x - 3

• y = 3x - 1/3

• y = -1/3x + 3

• y = -3x + 1/3

If a line crosses the y-axis at -2 and has a slope of 1/3, what is the equation?

• y = -1/3x + 2

• y = 3x - 1/3
