Writing Linear Equations with the Point-Slope Formula

What is the point-slope formula?

• y - y1 = m(x - x1)

• y = mx + b

• ax + by = c

• x = my + b

In the point-slope formula, what does 'm' represent?

• The x-intercept

• The slope

• The y-intercept

• The x-coordinate of a point

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

• Subtract the x-coordinate

• Combine like terms

• Distribute the slope

• Add the y-intercept

If a line passes through the point (2, 1) and has a slope of -2, what is the equation in slope-intercept form?

• y = 2x + 5

• y = -2x + 5

• y = 2x - 5

• y = -2x - 5

What is the next step after distributing the slope in the point-slope formula?

• Subtract the x-coordinate

• Add the y-intercept

• Isolate y

• Combine like terms

For a line passing through (-1, -2) with a slope of 6, what is the equation in slope-intercept form?

• y = 6x + 4

• y = -6x + 4

• y = 6x - 4

• y = -6x - 4

How do you handle negative values in the point-slope formula?

• Subtract them

• Use parentheses

• Add them directly

• Ignore them

What is the equation in slope-intercept form for a line passing through (-3, -3) with a slope of 1/3?

• y = 1/3x + 2

• y = -1/3x + 2

• y = 1/3x - 2

• y = -1/3x - 2

What is the final step in converting point-slope form to slope-intercept form?

• Distribute the slope

• Combine like terms

• Add the y-intercept

• Isolate y
