Slope and Y-intercept

Slope and Y-intercept

Ms. Santos Algebra 1

What is the Slope and Y-intercept in this equation y = 2x - 6?

• The slope is 2 (the slope is always next to the x-variable)

• The y-intercept is -6. (this is where the line crosses the y-axis)

Let's try from a word problem.

• You take a taxi from you house to the mall, it cost $5 when you get in the taxi and then it is $2 for each mile.

• What is the slope?

• What is the Y-intercept

• How much will it cost you to go 5 miles?

Answer

• The slope is $2

• the y-intercept is $5

• The equation is y = 2x + 5

• It would cost you $15 to travel 5 miles.
