Slope Intercept Form Review

Write the slope-intercept equation for a line with a slope of 2 and a y-intercept of -3.

• y = 2x - 3

• y = 3x - 2

• y = -2x + 3

• y = -3x + 2

How do you graph a line given its slope and y-intercept?

• Start at the y-intercept on the y-axis, then use the slope to find another point by rising and running.

• Begin at the origin and draw a horizontal line based on the slope.

• Plot the slope on the x-axis and connect it to the y-intercept.

• Use the slope to determine the x-intercept and plot that point.

What does the y-intercept (b) represent in a linear equation?

• The slope of the line.

• The point where the line crosses the x-axis.

• The point where the line crosses the y-axis, represented by the value of y when x = 0.

• The average value of y for all x values.

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

• m = (y2 - y1) / (x2 - x1)

• m = (x2 - x1) / (y2 - y1)

• m = (y1 + y2) / (x1 + x2)

• m = (y2 + y1) / (x2 - x1)

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

• y = mx + b

• y = ax^2 + bx + c

• y = m + b

• y = mx - b

What is the slope of the line represented by the equation y = -1/3x + 4?

• -1/3

• 1/3

• -4

• 4

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

• 1

• 2

• 3

• 4

What is the y-intercept of the line represented by the equation y = -2x + 5?

• 3

• 5

• 7

• -2

What does the slope (m) represent in a linear equation?

• The slope represents the rate of change of y with respect to x, indicating how steep the line is.

• The slope represents the y-intercept of the line.

• The slope indicates the maximum value of y in the equation.

• The slope shows the distance between two points on the line.

If a line has a slope of -4/5, what does this indicate about its direction?

• 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.
