Slope of a Line Using Graphs and Tables

To write an equation you need two pieces of information- the slope (the change in y/x is it positive or negative) and the y-intercept (where the line crosses the y-axis). Write an equation for the following line Hint: use y = mx + b

Answer explanation

The line goes down, so the slope is negative.

2 down and over 3.

The line crosses the y-axis at positive 5, so the y-intercept is + 5.

What is the first step in graphing a linear function using an equation?

• Plot the x and y coordinates

• Find the x-intercept and y-intercept

• Calculate the area under the curve

• Determine the slope and y-intercept

Given the table of values: x | y -2 | -4 0 | 1 2 | 6 What is the slope of the linear function?

• 5/2

• 7/2

• 4/3

• -3/2
