VETS Algebra I Mid-term Exam- Mr. Melendez & Mr. Leffler

Front

What is the equation of the line with a slope of -2 and a y-intercept of 4?

Back

y = -2x + 4

Front

What is the first mistake in the equation if the error occurs during division by -50?

Back

Dividing by -50

Front

Why do parallel lines never intersect?

Back

They have the same slopes.

Front

What is the slope of the line represented by the equation 6x - 2y = 18?

Back

Slope = 3

Front

What is the y-intercept of the line represented by the equation 6x - 2y = 18?

Back

y-intercept = -9

Front

What is the general form of a linear equation?

Back

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

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What does it mean for two lines to be perpendicular?

Back

Their slopes are negative reciprocals of each other.

Front

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

Back

y = mx + b

Front

What is the significance of the y-intercept in a linear equation?

Back

It is the point where the line crosses the y-axis.
