Semester 1 Final Review (Units 1 & 2)

Front

What is the slope of a line that is perpendicular to a line with slope m = 5/8?

Back

-8/5

Front

What does it mean when an equation has 'No solution'?

Back

It means that there are no values for the variable that satisfy the equation.

Front

Convert the equation y + 5 = -3(x - 6) into slope-intercept form.

Back

y = -3x + 13

Front

How do you find the equation of a line that passes through two points, (8, 5) and (9, -1)?

Back

Use the slope formula to find the slope, then use point-slope form to find the equation.

Front

Write the inequality in interval notation for the graph that shows values between -4 and -1, including -4 but not -1.

Back

[-4, -1)

Front

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

Back

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

Front

What does slope-intercept form of a line look like?

Back

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

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

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.

Front

What does it mean for a system of equations to have 'All real numbers' as a solution?

Back

It means that the equations represent the same line, and every point on that line is a solution.
