Solving Systems Review

Front

How is a coordinate pair ordered?

Back

(x, y)

Front

What is the slope-intercept form of a line?

Back

y = mx + b

Front

What are the x and y intercepts for the equation 4x - 10y = 20?

Back

x-intercept = 5, y-intercept = -2

Front

What is the standard form of a linear equation?

Back

Ax + By = C

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

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

Back

The value of y when x = 0.

Front

What is the difference between standard form and slope-intercept form?

Back

Standard form is Ax + By = C; slope-intercept form is y = mx + b.

Front

How do you convert from slope-intercept form to standard form?

Back

Rearrange the equation to get Ax + By = C.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope but different y-intercepts.
