Front

Find the slope of the line that passes through (1, -19) and (-2, -7)

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1). For points (1, -19) and (-2, -7), m = (-7 - (-19)) / (-2 - 1) = 12 / -3 = -4.

Factor x^2 + 7x + 10

Back

The expression factors to (x + 2)(x + 5).

Front

Which graph best shows the solution set for y ≤ \frac{7}{3}x - 2?

Back

The solution set includes all points below the line y = \frac{7}{3}x - 2, including the line itself.

What is (3y^4)²?

Back

(3y^4)² = 9y^8.

Front

Match the system to the graph: y ≤ 3x and y ≤ -2x + 4

Define slope in the context of a linear equation.

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

Explain the difference between a function and a relation.

Back

A function is a specific type of relation where each input (x-value) is associated with exactly one output (y-value).

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.
