Semester 1 Final Part 3

Front

Solve for x: (2x - 3) / 4 = 9

Back

x = 19.5

Front

What is the slope of a line parallel to m = 3/4?

Back

The slope is 3/4.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

Back

Domain: {-4, 0, 1, 2}; Range: {-4, -3, 1}

Front

Solve the equation: 4 - 6x - 2 = -2(3x-1)

Back

Infinitely many solutions.

Front

Which equation has no solution? 3(2x+1) = 6x+1

Back

This equation has no solution.

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

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

Back

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

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.

Front

What is the solution to the equation 2x + 1 = 5x - 3?

Back

x = 4.
