Mastery Check Review: Equations from Tables & Proportional

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

What does 'm' represent in the equation y=mx+b?

Back

The slope of the line, indicating the rate of change of y with respect to x.

Front

What does 'b' represent in the equation y=mx+b?

Back

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

Front

How do you determine if a relationship is proportional?

Back

A relationship is proportional if it can be expressed as y=kx, where k is a constant.

Front

What is a nonproportional relationship?

Back

A relationship that cannot be expressed as y=kx; it has a y-intercept other than zero.

Front

Write the equation for the table in y=mx+b form: (0, 2), (1, 6), (2, 10).

Back

y=4x+2

Front

Write the equation for the table in y=mx+b form: (0, 23), (1, 17), (2, 11).

Back

y=-6x+23

Front

Write the equation for the table in y=mx+b form: (0, 1), (1, 4), (2, 7).

Back

y=3x+1

Front

What is the first step to find the equation from a table of values?

Back

Identify the slope (m) by calculating the change in y over the change in x.

Front

What is the significance of the y-intercept in a linear equation?

Back

It indicates the starting value of y when x is zero.
