End of Year- Math 8 Review

Front

What is the equation of a line with a slope of -2/3 and a y-intercept of 5?

Back

y = -2/3x + 5

Front

What is the sum of the interior angles of a triangle?

Back

180 degrees

Front

How do you calculate the perimeter of a rectangle with length x + 4 and width x + 1?

Back

Perimeter = 2(length + width) = 2((x + 4) + (x + 1)) = 4x + 10

Front

What is the slope of a line if the change in y is 4 and the change in x is 1?

Back

Slope = 4/1 = 4

Front

What is the slope of a line represented by the equation y = -3/2x + 5?

Back

-3/2

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y divided by the change in x.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

How do you find the slope from a table of values?

Back

Calculate the change in y divided by the change in x between two points.
