Back

15.75 feet

Front

Write an equation to represent a line where y is 5 more than ⅓ of x.

Back

y = (1/3)x + 5

Front

What are the slope (m) and y-intercept (b) of a line if m = -0.04 and b = 15?

Back

m = -0.04, b = 15

Front

What does a zero slope indicate about a graph?

Back

A zero slope indicates that the line is horizontal.

Front

What is the scale factor used on a blueprint if the actual length of an object is 78 feet and the length on the blueprint is 13 inches?

Back

Front

How do you convert a mixed number like 12¾ to a decimal?

Back

12¾ = 12 + 0.75 = 12.75

Front

What is the formula for calculating the slope (m) of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What does the y-intercept represent in a linear equation?

Back

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

Front

How can you determine if a relationship is linear from a table of values?

Back

If the change in y divided by the change in x is constant, the relationship is linear.

Front

What is the significance of the slope in a linear equation?

Back

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