Math 8 Unit 3: Writing Linear Equations from Tables & Graphs

Front

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

Back

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

Front

How do you identify the slope from the equation y = mx + b?

Back

The slope (m) is the coefficient of x in the equation.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept (b) is the point where the line crosses the y-axis.

Front

Write a linear equation with a slope of -3 and a y-intercept of 5.

Back

y = -3x + 5

Front

What is the slope of the line represented by the equation y = 2x + 4?

Back

The slope is 2.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

What is the slope of the line represented by the equation y = -4x + 1?

Back

The slope is -4.

Front

How do you determine the equation of a line from a graph?

Back

Identify the slope and y-intercept from the graph, then use the slope-intercept form y = mx + b.

Front

Write the equation of a line with a slope of 1/2 and a y-intercept of 3.

Back

y = 1/2x + 3

Front

What does a positive slope indicate about a line?

Back

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