FLASHCARD QUESTION
Front
What is the slope-intercept form of a linear equation?
Back
The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.
2.
FLASHCARD QUESTION
Front
How do you find the slope from an equation in point-slope form?
Back
The slope can be identified directly from the equation in point-slope form, which is y - y1 = m(x - x1), where m is the slope.
3.
FLASHCARD QUESTION
Front
What does the slope of a line represent?
Back
The slope represents the rate of change of y with respect to x; it indicates how steep the line is.
4.
FLASHCARD QUESTION
Front
What is the y-intercept of a linear equation?
Back
The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form.
5.
FLASHCARD QUESTION
Front
How do you convert from standard form to slope-intercept form?
Back
To convert from standard form Ax + By = C to slope-intercept form, solve for y to get y = (-A/B)x + (C/B).
6.
FLASHCARD QUESTION
Front
What is the solution to the inequality 3(x - 3) ≤ 2(x + 2)?
Back
The solution is x ≤ 13.
7.
FLASHCARD QUESTION
Front
How do you determine if a point lies on a line represented by an equation?
Back
Substitute the x and y coordinates of the point into the equation. If the equation holds true, the point lies on the line.
