How to Find Slope | Math with Mr. J

What does the slope of a line measure?

• The length of the line

• The steepness of the line

• The area under the line

• The width of the line

A line goes up 3 units and moves right 4 units. What is its slope?

• 4/3

• 3/4

• -3/4

• -4/3

If you calculate the slope of a line using two different pairs of points, what should be true about the resulting fractions?

• They will always be different.

• They will always be the same, even if not simplified.

• They will be equivalent fractions that simplify to the same value.

• One will be positive and the other negative.

A line goes down 2 units and moves right 5 units. What is its slope?

• 2/5

• 5/2

• -2/5

• -5/2

What is the slope of the line shown in the graph?

• -6

• 6

• -1/6

• 1/6

What is the slope of the line shown in the graph?

• 3/10

• -10/3

• 10/3

• -3/10

Which formula is used to calculate the slope (m) of a line given two points (x1, y1) and (x2, y2)?

• m = (x2 - x1) / (y2 - y1)

• m = (y2 + y1) / (x2 + x1)

• m = (y2 - y1) / (x2 - x1)

• m = (x1 - y1) / (x2 - y2)

What is the slope of the line that passes through the points (3, 1) and (5, 8)?

• 7/2

• 2/7

• 9/8

• 8/9

What is the slope of the line passing through the points (3,1) and (5,8)?

• 7/2

• 2/7

• -7/2

• -2/7

When calculating the slope using two points, (x1, y1) and (x2, y2), what happens if you switch the order of the points (making (x2, y2) the first point and (x1, y1) the second)?

• The slope becomes negative

• The slope becomes positive

• The slope remains the same

• The slope cannot be calculated
