Math 6th grade slopes

What is the formula to calculate the slope of a line?

• (x2 - x1) / (y2 - y1)

• (y2 - y1) * (x2 - x1)

• (y2 - y1) / (x2 - x1)

• (y1 - y2) / (x1 - x2)

If a line has a positive slope, how does it slant?

• Downwards

• Horizontally

• Upwards

• Curved

If a line has a negative slope, how does it slant?

• It slants upwards from right to left.

• It slants downwards from left to right.

• It slants horizontally.

• It slants upwards from left to right.

What does it mean if a line has a slope of 0?

• The line has a negative slope.

• The line is vertical.

• The line is horizontal.

• The line has a positive slope.

What does it mean if a line has an undefined slope?

• The line is horizontal.

• The line has a positive slope.

• The line is vertical.

• The line has a negative slope.

Calculate the slope of a line passing through the points (2, 3) and (5, 9).

• The slope of the line passing through the points (2, 3) and (5, 9) is (9 - 2) / (5 - 3) = 7 / 2.5 = 2.8.

• The slope of the line passing through the points (2, 3) and (5, 9) is (3 - 2) / (9 - 5) = 1 / 4 = 0.25.

• The slope of the line passing through the points (2, 3) and (5, 9) is (5 - 2) / (9 - 3) = 3 / 6 = 0.5.

• The slope of the line passing through the points (2, 3) and (5, 9) is (9 - 3) / (5 - 2) = 6 / 3 = 2.

Determine the slope of a line parallel to the line y = 2x + 5.

• 2

• 6

• 4

• 3

Determine the slope of a line perpendicular to the line y = -3x + 4.

• 4

• 1/3

• 0

• -3

If the slope of a line is 3/4, what is the rise and run?

• Rise = 5, Run = 2

• Rise = 2, Run = 5

• Rise = 4, Run = 3

• Rise = 3, Run = 4

Explain how to graph a line using its slope and a point on the line.

• Use the slope to find the y-intercept and plot the point

• Plot the given point and use the slope to find a third point

• Plot the given point and use the slope to find a second point, then connect the two points to draw the line.

• Draw a line through the given point with a random slope
