Understanding Slope-Intercept Form

The video tutorial explains how to graph a linear equation using the slope-intercept form, Y = MX + B. It begins by converting the equation 2X - Y = -1 into slope-intercept form by isolating Y. The slope (M) and Y-intercept (B) are identified as +2 and +1, respectively. The tutorial then demonstrates how to graph the line by plotting the Y-intercept and using the slope to find additional points. The process is summarized, and viewers are informed that another example will be covered in the next video.

What is the slope-intercept form of a linear equation?

• B = YX + M

• Y = MX + B

• Y = B + MX

• X = MY + B

What is the first step to rearrange the equation 2X - Y = -1 into slope-intercept form?

• Add 2X to both sides

• Multiply both sides by 2

• Divide both sides by Y

• Subtract 2X from both sides

After rearranging the equation, what operation is performed to solve for Y?

• Divide by -1

• Multiply by -1

• Subtract 1

• Add 1

What is the y-intercept of the equation Y = 2X + 1?

• (1, 2)

• (0, 2)

• (1, 0)

• (0, 1)

How is the slope of 2/1 interpreted in terms of graphing?

• Up 2, Right 1

• Down 2, Left 1

• Up 1, Right 2

• Down 1, Left 2

What is the significance of the slope in a linear equation?

• It is always a positive number

• It shows the x-intercept

• It indicates the steepness and direction of the line

• It determines the y-intercept

What is the first point plotted on the graph when using the slope-intercept form?

• The x-intercept

• Any random point

• The origin

• The y-intercept

What does the denominator in the slope fraction represent?

• Change in y

• Change in x

• The y-intercept

• The x-intercept

What is the final form of the equation after solving for Y?

• Y = 1X + 2

• Y = 2X + 1

• Y = X - 2

• Y = -2X - 1
