Algebra 1 Unit 4 Review Insights

The video tutorial covers graphing linear equations, focusing on slope-intercept and point-slope forms. It explains how to find the slope and y-intercept from equations and demonstrates graphing techniques using intercepts. The tutorial also includes a review of key concepts and provides practice problems to reinforce learning.

What does the 'M' in slope-intercept form represent?

• The slope of the line

• The x-intercept of the line

• The point on the line

• The y-intercept of the line

In the equation y = 6x - 8, what is the y-intercept?

• -6

• -8

• 0

• 6

How do you find the slope of an equation not in y = form?

• By solving for y first

• By adding x to both sides

• By subtracting x from both sides

• By multiplying both sides by y

What is the new slope when the original slope is cut in half?

• 8

• -8

• 4

• -4

How do you graph y = -2x - 4 using slope and y-intercept?

• Start at -4 on the y-axis, then go down 2 and right 1

• Start at -2 on the y-axis, then go down 4 and right 1

• Start at -4 on the y-axis, then go up 2 and right 1

• Start at 0 on the y-axis, then go down 2 and right 4

What is the x-intercept when graphing using intercepts?

• Where x is 1

• Where y is 0

• Where y is 1

• Where x is 0

How is the y-intercept identified in the equation y = mx + b?

• As the constant term b

• As the variable x

• As the coefficient of x

• As the slope m

What happens to the graph if the slope is changed to 2 and the y-intercept remains the same?

• The y-intercept shifts upwards

• The graph becomes steeper

• The graph becomes less steep

• The x-intercept remains unchanged

How does subtracting 3 from f(x) = x affect its graph?

• Shifts it 3 units up

• Makes it less steep

• Shifts it 3 units down

• Makes it steeper

What is the slope of a line that rises 1000 units and runs 5 units?

• 50

• 5

• 100

• 200
