Exploring Slope Intercept Form in Algebra

The video tutorial explains how to convert a linear equation from standard form to slope-intercept form. It demonstrates identifying the slope and Y-intercept and graphing the equation. A practice problem is provided to reinforce the concepts.

What is the first step in converting an equation to slope-intercept form?

• Solve for y to isolate it on one side of the equation

• Plot the y-intercept on a graph

• Identify the slope and y-intercept

• Divide every term by the coefficient of y

What does the slope represent in the equation y = mx + b?

• The total distance the line covers

• The vertical change per unit of horizontal change

• The x-intercept of the line

• The y-intercept of the line

How do you plot the first point when graphing a linear equation?

• Use the slope to find the point

• Plot the point where x equals zero

• Choose any point on the x-axis

• Plot the y-intercept

What does a slope of -2 indicate about the direction of the line?

• The line moves up to the right

• The line is vertical

• The line is horizontal

• The line moves down to the right

In the equation 3x - 4y = 12, what is the first step to convert it into slope-intercept form?

• Identify the slope directly

• Divide each term by -4

• Multiply each term by 4

• Move the 3x to the other side of the equation

What is the slope of the equation after converting 3x - 4y = 12 into slope-intercept form?

• -4/3

• 4/3

• -3/4

• 3/4

How does dividing each term by the coefficient of y help in converting an equation to slope-intercept form?

• It eliminates the x variable from the equation

• It isolates y on one side of the equation

• It changes the slope of the line

• It finds the x-intercept of the equation

What is the y-intercept of the equation after converting 3x - 4y = 12 into slope-intercept form?

• -3

• 3

• -4

• 4

When graphing, how do you use the slope to find the next point?

• Move horizontally based on the slope and then vertically

• Use the slope as the y-coordinate for the next point

• Use the slope as the x-coordinate for the next point

• Move vertically based on the slope and then horizontally

What does a y-intercept of -3 indicate about the graph?

• The line is horizontal at y = -3

• The slope of the line is -3

• The line crosses the x-axis at -3

• The line crosses the y-axis at -3
