VETS Algebra I Mid-term Exam- Mr. Melendez

Front

What is the error in the expression: 2x + 3x?

Back

The error is adding 2x to 3x, which should be combined to 5x.

Front

Write the equation of a line with a slope of 2 that goes through the point (-4, 3).

Back

The equation is y = 2x + 11.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C.

Front

Write the equation of a line that has an undefined slope and goes through the point (9, -5).

Back

The equation is x = 9.

Front

What is the slope of the line passing through the points (3,5) and (-1,7)?

Back

The slope is -1/2.

Front

Define slope in the context of a linear equation.

Back

Slope is the ratio of the rise (change in y) to the run (change in x) between two points on a line.

Front

What does the term 'y-intercept' refer to?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

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

Back

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

Front

What is the difference between a positive and negative slope?

Back

A positive slope indicates that the line rises from left to right, while a negative slope indicates that the line falls from left to right.

Front

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

Back

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