Write y=mx+b Equations Using Tables and More

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 in the equation y = 3x + 2?

Back

The slope (m) is 3.

Front

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

Back

The y-intercept (b) represents the value of y when x is 0.

Front

If a function is represented by the equation y = -2x + 5, what is the slope?

Back

The slope is -2.

Front

How can you represent a function that starts at 150 and increases by 40 each month?

Back

The function can be represented as y = 40x + 150.

Front

What is the equation for a driving range that charges $4 plus $2.75 per bucket of balls?

Back

The equation is c = 2.75b + 4.

Front

In the equation y = 6x - 4, what is the y-intercept?

Back

The y-intercept is -4.

Front

How do you convert a table of values into a linear equation?

Back

Identify the slope (change in y/change in x) and the y-intercept from the table.

Front

What does it mean if the slope of a line is negative?

Back

It means that as x increases, y decreases.

Front

If you have the equation y = 2x + 2, what is the value of y when x = 3?

Back

When x = 3, y = 2(3) + 2 = 8.
