Unit 4 Review #3

Front

Write a linear equation with a slope of 1 and the y-intercept of -7.

Back

y = x - 7

Front

Write the linear equation for the points (-2, 7) and (6, -5).

Back

y = -3/2x + 4

Front

Identify the slope and y-intercept of the equation y = -3x.

Back

Slope: -3, Y-Intercept: 0

Front

What is the slope of the line given the points (-11, 7) and (-11, -2)?

Back

undefined

Front

What is the slope of the line given the points (-12, -1) and (-3, -4)?

Back

-1/3

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y divided by the change in x.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

How do you find the y-intercept of a linear equation in slope-intercept form?

Back

The y-intercept is the value of y when x = 0.
