Exploring Slope Intercept and Point Slope Forms

What is the general form of the slope-intercept equation?

• y = m + bx

• y = b + mx

• y = mx + b

• y = mx - b

In the slope-intercept form equation y = mx + b, what does 'm' represent?

• The x-intercept

• The constant term

• The y-intercept

• The slope

What is the formula for point-slope form?

• y + y1 = m(x + x1)

• y = m(x + x1)

• y = mx + b

• y - y1 = m(x - x1)

What two pieces of information do you need to use the point-slope form?

• Two slopes

• A slope and a y-intercept

• A point and a slope

• Two points

If given a point (4, 7) and a slope of 3, what is the first step in using point-slope form?

• Substitute the point and slope into y - y1 = m(x - x1)

• Find the y-intercept

• Substitute the point and slope into y = mx + b

• Find the x-intercept

What should you do after distributing the slope in the point-slope form equation?

• Combine like terms

• Divide by the slope

• Find the y-intercept

• Find the x-intercept

What is the formula to find the slope when given two points?

• x2 + x1 / y2 + y1

• y2 + y1 / x2 + x1

• x2 - x1 / y2 - y1

• y2 - y1 / x2 - x1

Given points (9, 5) and (8, 6), what is the slope?

• 1

• -1

• 0

• 2

When converting two points into slope-intercept form, what is the final step?

• Find the x-intercept

• Combine like terms

• Distribute the slope

• Isolate y

If the final slope-intercept form is y = -x + 14, what is the slope?

• 1

• -1

• 14

• -14
