Front

What is the solution to the equation represented by the points (1, -1)?

Back

(1, -1)

Front

What is the equation for a line with a slope of -2 and a y-intercept of 5?

Back

y = -2x + 5

Front

What type of relationship does the equation y = 75x represent?

Back

Proportional

Front

How do you find the slope of a line given two points, (10, 1) and (5, 2)?

Back

Slope = (y2 - y1) / (x2 - x1) = (2 - 1) / (5 - 10) = -1/5

Front

If a ladder is 13 feet long and leans against a 12-foot wall, how far is the base of the ladder from the wall?

Back

5 feet

Front

What is the definition of a proportional relationship in mathematics?

Back

A relationship where the ratio of two variables is constant.

Front

What is the formula for calculating the slope of a line?

Back

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

Front

What does it mean if an equation is nonproportional?

Back

It means that the relationship between the variables does not maintain a constant ratio.
