Equation of a Line Flashcard

Front

What is the formula to find the percentage of a number?

Back

Percentage = (Part/Whole) × 100

Front

Solve for x: 48 is what percent of 60?

Back

x = 80%

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols like <, >, ≤, or ≥.

Front

Solve the inequality: -7 - 3x ≥ -10

Back

x ≤ 1

Front

What does it mean to write an algebraic expression?

Back

An algebraic expression is a combination of numbers, variables, and operations that represents a value.

Front

Write the algebraic expression for: twice the sum of x and 12.

Back

2(x + 12)

Front

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

Back

Point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

Write the point-slope form of the equation of the line through (1, 2) with slope 2.

Back

y - 2 = 2(x - 1)

Front

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

Back

Slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.

Front

Write the slope-intercept form of the equation of the line through (3, -2) with slope -2.

Back

y = -2x + 4
