Vocabulary: Tell whether the equation is in slope-intercept, point-slope, or standard form.
y + 2 = -2(x - 1)

slope-intercept form

point-slope form

standard form

Vocabulary: Tell whether the equation is in slope-intercept, point-slope, or standard form.
y = -\frac{1}{4}x + 9

point-slope form

standard form

slope-intercept form

Vocabulary: Tell whether the equation is in slope-intercept, point-slope, or standard form.
-x - 2y = 1

point-slope form

slope-intercept form

standard form

Vocabulary: Tell whether the equation is in slope-intercept, point-slope, or standard form.
y - 3 = 4x

point-slope form

slope-intercept form

standard form

Understanding: Which form would you use to write the equation of a line if you knew its slope and x-intercept? Explain.

Understanding: If the intercepts of a line are (a, 0) and (0, b), what is the slope of the line? Assume that a and b are both greater than 0.

Enter only the slope, in simplified fraction form. The fraction will include a and b.

Error Analysis: Your friend says the line y = -2x + 3 is perpendicular to the line x + 2y = 8. Do you agree? Explain.

No; After converting the second equation to slope-intercept form, we can see that its slope is -1/2. Since -2 and -1/2 are not opposite reciprocals, the lines are not perpendicular.

Yes; After converting the second equation to slope-intercept form, we can see that its slope is 1/2. Since -2 and 1/2 are opposite reciprocals, the lines are perpendicular.
