Front

Identify the slope and the point from the equation: y - 10 = - 5/2 (x + 5)

Back

m= -5/2, pt: (-5, 10)

Front

Which equation matches the table?

Back

y = 3x + 9

Front

This is a graph of which inequality? y < 4X - 2

Back

y < 4X - 2

Front

What is the definition of a function?

Back

Every input has only ONE output.

Front

What is the formula for the slope of a line?

Back

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

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be represented by a straight line on a graph.

Front

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

Back

The y-intercept is the value of y when x = 0, represented by b.

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 and solve for x.

Front

What is the difference between independent and dependent variables?

Back

Independent variables are inputs (x), while dependent variables are outputs (y).
