Writing Equations in Slope-Intercept Form

Why is the slope intercept form considered the most useful for graphing equations?

• It is the easiest to graph and understand at a glance.

• It is rarely used in real-world applications.

• It is the most complex form.

• It is the only form for writing equations.

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

• The y-intercept

• The slope

• The x-intercept

• The constant term

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

• The slope

• The x-intercept

• The variable term

• The y-intercept

Given the equation y = 0.7x - 4.9, what is the slope?

• 0.7

• -4.9

• -0.7

• 4.9

Given the equation y = 0.7x - 4.9, what is the y-intercept?

• -0.7

• -4.9

• 0.7

• 4.9

What is the first step in rearranging the equation -9x + y = 12 to slope intercept form?

• Subtract 9x from both sides

• Add 9x to both sides

• Multiply both sides by 3

• Divide both sides by 3

If an equation in slope intercept form has no constant term, where does the line cross the y-axis?

• At y = 10

• At the origin

• At y = 1

• At y = -1

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

• 3

• 1

• 5

• 0
