Semester Exam Review (Algebra 1 H)

Front

What is the formula to find the slope of a line?

Back

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

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

How do you write an equation in slope-intercept form?

Back

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

Front

What is the y-intercept of the line y = 6x - 3?

Back

The y-intercept is -3.

Front

Convert the equation 5x - 3y = -9 to slope-intercept form.

Back

y = (5/3)x + 3.

Front

What is the slope of the line represented by the equation 2x + 7y = -21?

Back

The slope is -2/7.

Front

Which point is NOT part of the solution set for the inequality y < 2x + 1?

Back

(0, -2) is NOT part of the solution set.

Front

What does it mean for a point to be part of the solution set of an equation?

Back

It means that when the coordinates of the point are substituted into the equation, the equation holds true.

Front

How do you determine if a point lies on a line given by an equation?

Back

Substitute the x and y values of the point into the equation. If the equation is satisfied, the point lies on the line.

Front

What is the significance of the slope in real-world applications?

Back

The slope can represent speed, growth rate, or any other rate of change in various contexts.
