Writing Equations in Slope-Intercept Form

What is the general form of a linear equation?

• y = mx^2 + b

• y = ax^2 + bx + c

• y = ax + b

• y = mx + b

If the slope (m) is 1/3 and the Y-intercept (b) is 2, what is the equation?

• y = 1/3x + 2

• y = 3x - 2

• y = 3x + 2

• y = 1/3x - 2

What does a slope of zero indicate about the graph of the equation?

• The graph has no Y-intercept.

• The graph is a horizontal line.

• The graph is a vertical line.

• The graph passes through the origin.

If the slope is 2 and the Y-intercept is 0, what is the simplified form of the equation?

• y = 2x

• y = 2x + 0

• y = 2x - 0

• y = 0x + 2

How do you find the slope from a graph?

• By measuring the distance between two points.

• By counting the rise over the run between two points.

• By identifying the Y-intercept.

• By finding the X-intercept.

If a line rises 1 unit and runs 2 units, what is the slope?

• 1/3

• 2

• 1/2

• 1

Given a graph with a Y-intercept of -4 and a slope of 1/5, what is the equation?

• y = 1/5x + 4

• y = 5x - 4

• y = 1/5x - 4

• y = -1/5x - 4

If a line crosses the Y-axis at 4 and has a slope of -1, what is the equation?

• y = x - 4

• y = -x + 4

• y = -4x + 1

• y = 4x - 1

What is the equation of a line with a Y-intercept of -4 and a slope of -1?

• y = 4x + 1

• y = -x - 4

• y = x + 4

• y = -4x - 1

What is the key difference between a line with zero slope and a line with zero Y-intercept?

• Zero slope means the line is vertical; zero Y-intercept means it has no slope.

• Zero slope means the line is horizontal; zero Y-intercept means it has no slope.

• Zero slope means the line is horizontal; zero Y-intercept means it passes through the origin.

• Zero slope means the line is vertical; zero Y-intercept means it passes through the origin.
