In the equation y=5x-6, what is 'b'?

• -6

• -5

• 0

• 6

Given a slope of 2/3 and a y-intercept of -3, what is the equation of the line?

• y = 2/3x - 3

• y = 3/2x + 3

• y = -2/3x - 3

• y = 2/3x + 3

What is the slope of the line represented by the equation y = -3x + 1?

• -2

• -3

• 1

• 3

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

• y = mx + b, where m is the slope and b is the y-intercept.

• y = ax^2 + bx + c, where a, b, and c are constants.

• y = m(x - b) + b, where m is the slope and b is a point on the line.

• y = mx + c, where m is the slope and c is the y-intercept.

If the slope of a line is undefined, what does this mean?

• The line is horizontal.

• The line is vertical.

• The line has a positive slope.

• The line has a negative slope.

What is the equation of the line represented by the graph?

• y = x + 2

• y = 2x + 1

• y = -x + 3

• y = 3x - 2

What does a negative slope indicate about a line?

• The line rises as it moves from left to right.

• The line falls as it moves from left to right.

• The line is horizontal.

• The line is vertical.

How do you find the slope from two points (x1, y1) and (x2, y2)?

• Slope (m) = (y2 - y1) / (x2 - x1).

• Slope (m) = (x2 - x1) / (y2 - y1).

• Slope (m) = (y1 + y2) / (x1 + x2).

• Slope (m) = (y2 + y1) / (x2 - x1).

What is the relationship between perpendicular lines in terms of slope?

• Perpendicular lines have slopes that are equal to each other.

• Perpendicular lines have slopes that are negative reciprocals of each other.

• Perpendicular lines have slopes that add up to one.

• Perpendicular lines have slopes that are both positive.

What is the y-intercept of the line represented by the equation y = 2x - 4?

• (0, -4)

• (0, 0)

• (2, -4)

• (-2, 0)
