Intercepts and Inequalities in Graphing

The video tutorial guides viewers through sketching linear equations on a graph. It begins with setting up equations, finding x and y intercepts, and graphing lines with appropriate shading. The tutorial covers two equations, explaining the process of solving and graphing each. The instructor emphasizes understanding intercepts and the significance of inequality signs in graphing. The video concludes with an offer for additional help if needed.

• 1

How do you find the y-intercept of the equation y = 1.5x - 3?

• Set x to zero

• Set y to one

• Set y to zero

• Set both x and y to zero

What is the y-intercept of the equation y = 1.5x - 3?

• 1.5

• 3

• -3

• 0

Why is a dotted line used for the inequality y > 1.5x?

• Because it excludes the line

• Because it is a horizontal line

• Because it includes the line
