Algebra Semester 1 Review

Front

What is the slope of the line represented by the equation y + 1 = -3(x - 5)?

Back

The slope is -3.

Front

Simplify the expression: 4 + 0.

Back

4

Front

Simplify the expression: 24 ÷ 4 ⋅ 2 + (3² - 1 + 6).

Back

The result is 26.

Front

Find the slope of the line that passes through the points (-3, -4) and (7, 6).

Back

The slope is 1.

Front

How do you graph the equation y = -3x + 15?

Back

Plot the point (0,15). Then go down 3 right 1 to plot the next point.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does it mean if a line has an undefined slope?

Back

An undefined slope indicates a vertical line where x does not change.

Front

What is the y-intercept of the equation y = -3x + 15?

Back

The y-intercept is 15.

Front

What is the result of simplifying the expression: 3(2 + 4) - 5?

Back

The result is 15.

Front

How do you convert the equation y = mx + b into slope-intercept form?

Back

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