Understanding Slope and Y-Intercept

The video tutorial covers the basics of slope-intercept form, explaining how to identify the slope and y-intercept from an equation. It provides examples to illustrate these concepts, including how to complete an equation when given a slope and y-intercept. The tutorial emphasizes understanding the form y = mx + b and applying it to solve problems.

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

• y = mx + b

• y = b + mx

• x = my + b

• b = mx + y

In the equation y = -4x - 3, what is the slope?

• -4

• 3

• 4

• -3

How do you identify the y-intercept in the equation y = mx + b?

• It is the coefficient of x

• It is the constant term b

• It is the value of m

• It is the sum of m and b

What is the y-intercept of the equation y = -3x - 2?

• 0

If x = 0, what does the y-intercept represent on a graph?

• The slope of the line

• The point where the line crosses the y-axis

• The point where the line crosses the x-axis

• The midpoint of the line

In the context of a graph, what is the y-value when x is zero?

• The x-intercept

• The y-intercept

• The slope

• The origin

What is the equation of a line with a slope of 5 and a y-intercept of 4?

• y = 4x - 5

• y = 5x - 4

• y = 4x + 5

• y = 5x + 4

How do you write the equation of a line if you know the slope and y-intercept?

• x = my + b

• b = mx + y

• y = mx + b

• y = mx - b
