Semester 1 Final Test

Front

Find the slope of the line represented by the equation 2x - 3y = 6.

Back

The slope is 2/3.

Front

Find the slope of the line that passes through the points (-3, -4) and (7, 6).

Back

The slope is 1.

Front

What is the slope-intercept form of a line?

Back

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

Front

Write the equation of the line with slope -4 passing through the point (-1, 5).

Back

The equation is y - 5 = -4(x + 1).

Front

What is an exterior angle in a triangle?

Back

An exterior angle is formed by one side of a triangle and the extension of an adjacent side.

Front

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

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does it mean for a line to be undefined in slope?

Back

A line is undefined in slope when it is vertical, meaning it goes straight up and down.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

Define remote interior angles in relation to exterior angles.

Back

Remote interior angles are the two angles inside a triangle that are not adjacent to the exterior angle.

Front

What is the formula for point-slope form of a line?

Back

The point-slope form is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
