Front

What is the solution to the system of equations graphed by Sage?

Back

(-3,-8)

Front

What is the solution to the equation represented by the point?

Back

(1, -1)

Front

Which system of equations matches the graph?

Back

x - y = -2 and x + y = 4

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

Solve the system of equations: 4x + 8y = 20 and -4x + 2y = -30.

Back

(7,-1)

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

How do you convert the equation y - 5 = 3(x - 1) into slope-intercept form?

Back

y = 3x + 2.

Front

What is the y-intercept of the equation y = 10x - 7?

Back

The y-intercept is -7.

Front

What does it mean for two lines to intersect?

Back

It means they have a common solution, which is the point of intersection.

Front

How can you determine if a point is a solution to a system of equations?

Back

Substitute the point into both equations; if both are true, it is a solution.
