Finding Slope and Y-Intercept from a Table

The video tutorial teaches how to find the slope and y-intercept from a table without graphing. It begins with an introduction to the concepts, followed by a detailed explanation of calculating the slope by determining the change in Y over the change in X. The tutorial then covers finding the y-intercept by identifying the Y value when X is zero. Finally, a practice problem is provided to reinforce the learning objectives.

How do you find the y-intercept from a table?

• Find the X value of 0 and look at the corresponding Y value

• Find the X value of 1 and look at the corresponding Y value

• Find the Y value of 1 and look at the corresponding X value

• Find the Y value of 0 and look at the corresponding X value

What is the y-intercept if the X value is 0 and the Y value is 7?

• 7

• 0

• 2

• 1

What is the equation of a line with a slope of 2 and a y-intercept of 7?

• y = 7x - 2

• y = 2x - 7

• y = 7x + 2

• y = 2x + 7
