UNIT 3 Exam Review 2024

Front

Write an equation given the slope -2 and the y-intercept (0, 5)

Back

y = -2x + 5

Front

What type of slope is represented by a horizontal line?

Back

Zero slope

Front

Find the equation of the line that passes through the points (3, 4) and (0, -5)

Back

y = 3x - 5

Front

Write an equation for the line in slope-intercept form containing the points (0, 3) and (-1, -5)

Back

y = 8x + 3

Front

Write an equation for the line graphed with a slope of -2/3 and y-intercept of 2

Back

y = -\frac{2}{3}x + 2

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).
