What is the y-intercept of this line?

• (-1,0)

• (0,-1)

• (0,1)

• (1,0)

• (2,2)

Answer explanation

The y-intercept of a line is the point where it crosses the y-axis, which occurs when x=0. The correct choice (0,-1) indicates that when x is 0, y is -1, making it the y-intercept.

What is the slope of this line?

• -5/4

• -4/5

• 4/5

• 5/4

Answer explanation

The slope of a line is calculated as the rise over run. In this case, the correct slope is 4/5, indicating that for every 5 units moved horizontally, the line rises 4 units vertically.

• 18x

Answer explanation

Using the distributive property, multiply 3 by each term inside the parentheses: 3 * 2x = 6x and 3 * 4 = 12. Therefore, the expression simplifies to 6x + 12, which is the correct answer.

What is the equation of this line?

• y = (3/2)x - 1

• y = (3/2)x + 1

• y = (2/3)x + 1

• y = (2/3)x - 1

Answer explanation

The line has a slope of 3/2 and a y-intercept of -1, which matches the equation y = (3/2)x - 1. The other options either have the wrong slope or y-intercept.

• 8w - 3

• 8w - 12

• -4w

• 4w

Answer explanation

To distribute 4(2w - 3), multiply 4 by each term inside the parentheses: 4 * 2w = 8w and 4 * -3 = -12. Thus, the expression simplifies to 8w - 12, which is the correct answer.

• no

• yes

Answer explanation

To check if (2, 6) is a solution of 3x - y = 0, substitute x = 2 and y = 6. This gives 3(2) - 6 = 6 - 6 = 0, which is true. Therefore, (2, 6) is a solution, and the correct answer is yes.
