Understanding Slope-Intercept Form

This tutorial covers graphing using the slope-intercept form, y = mx + b. It explains how to identify and plot the y-intercept and use the slope to find a second point on the graph. Two examples are provided: one with a fractional slope and another with an integer slope, demonstrating how to handle different scenarios when graphing lines.

What is the general form of the slope-intercept equation?

• y = ax^2 + bx + c

• y = mx + b

• y = a/x + b

• y = mx^2 + b

In the equation y = mx + b, what does 'b' represent?

• The slope

• The x-intercept

• The y-intercept

• The origin

How do you convert a whole number slope into a fraction?

• Divide by 2

• Multiply by 10

• Put it over 1

• Subtract 1

For the equation y = 3/5x - 1, what is the y-intercept?

• 0

• 5

• 3/5

• -1

In the equation y = 3/5x - 1, what is the slope?

• -1

• 3/5

• 1

• 5

When graphing y = 4x + 3, what is the first step?

• Plot the slope

• Plot the y-intercept

• Convert the slope to a fraction

• Draw the x-axis

How can you handle graphing when the slope takes you off the graph?

• Ignore the slope

• Use a different graph

• Change the slope

• Reverse the direction using negatives

What is the slope of the equation y = 4x + 3 when converted to a fraction?

• 4/3

• 1/4

• 4/1

• 3/4

What happens to the line if you reverse both the numerator and denominator of the slope?

• The line disappears

• The line remains the same

• The line shifts up

• The line shifts down

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

• 3

• 4

• 0

• 1
