Back

Yes, (3, 5) is a solution because when x=3, y=3+2=5.

How do you find the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

What does a slope of zero indicate about a line?

Back

A slope of zero indicates that the line is horizontal.

Front

Back

Substituting y=6 gives x+2(6)=10, so x=-2.

What is the definition of slope in a linear equation?

Back

Slope is the measure of the steepness of a line, represented as the ratio of the rise over the run.

What is the slope-intercept form of a linear equation?

Front

How can you determine if a line is vertical?

Back

A line is vertical if it has an undefined slope, which occurs when all x-values are the same.

Front

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

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form.

Front

What does it mean if a line has a negative slope?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.
