Understanding Linear Equations in Slope-Intercept Form

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

• y = a/x + b

• y = mx + b

• y = ax + b

• y = ax^2 + bx + c

If you are given a slope of 4 and a y-intercept of -3, what is the equation of the line?

• y = -3x + 4

• y = 4x + 3

• y = 3x - 4

• y = 4x - 3

How do you determine the slope from a graph?

• By finding the y-intercept

• By calculating the area under the line

• By counting the rise over run between two points

• By measuring the angle with the x-axis

What is the y-intercept of a line that crosses the y-axis at -2?

• -2

• 0

• 2

• 1

What is the first step in rearranging an equation to slope-intercept form?

• Subtract x from both sides

• Add 5 to both sides

• Distribute any terms inside parentheses

• Multiply both sides by 2
