Back

y = mx + b

Front

Write an equation in y = mx + b form for the total cost of x pounds of fruit from the orchard if Lee charges $3 for a basket and $2.50 for each pound of fruit.

Back

y = 2.50x + 3

Front

Solve for x: 13 = 8 + x

Back

x = 5

Front

What is the definition of slope in a linear equation?

Back

The slope (m) is the ratio of the rise (change in y) over the run (change in x).

Front

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

Back

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

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 standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does it mean if a linear equation has no solution?

Back

It means the lines represented by the equations are parallel and never intersect.
