Algebra SOL A.6 Review

Front

What is the slope of the line represented by the equation 3x + 5y = -7?

Back

The slope is -3/5.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Use the formula: slope = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line that goes through the points (3,-5) & (6, 4)?

Back

The slope is 3.

Front

Which equation represents a horizontal line passing through the point (7,5)?

Back

The equation is y = 5.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

How do you convert the equation 3x + 5y = -7 into slope-intercept form?

Back

Rearrange to y = -rac{3}{5}x - rac{7}{5}.

Front

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

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

If a line has a slope of 2, what does this mean?

Back

For every 1 unit increase in x, y increases by 2 units.
