Solve for x: 3(5x + 10) + 10 = 6x - (x + 10)

Back

x = -5

Front

What is the domain of the function represented by the ordered pairs (52,3), (72,4), (86,5), and (105,6)?

Back

{52, 72, 86, 105}

Front

Solve the system: y = 6x - 11 and -2x - 3y = -7

Back

(2, 1)

Front

Which function represents the same relationship as the table of points on a linear function?

Back

m(x) = 5x - 12.5

Front

Write a system of equations for Sarah's lawn mowing: $20 for small lawns and $30 for large lawns, earning $140 for 6 lawns.

Back

20x + 30y = 140, x + y = 6

Front

What is a linear function?

Back

A function that graphs to a straight line, defined by the equation y = mx + b.

Front

Define the slope of a line.

Back

The slope (m) is the ratio of the rise (change in y) over the run (change in x) between two points on a line.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

Front

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

Back

Set y = 0 in the equation and solve for x.

Front

What does it mean for a system of equations to be consistent?

Back

A system is consistent if it has at least one solution.
