IM 1: Unit 3 (Part 2) Review (Final)

Front

What is the Point-Slope form of a linear equation?

Back

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

Front

What is the Slope-Intercept form of a linear equation?

Back

The Slope-Intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the Standard form of a linear equation?

Back

The Standard form is given by the equation Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

How do you identify a vertical shift in a linear equation?

Back

A vertical shift occurs when the constant term in the equation changes, affecting the y-intercept.

Front

If a line changes from y = 2x + 4 to y = -1/2x - 2, what is the vertical shift?

Back

The vertical shift is down by 6 units.

Front

How do you find the point where two linear equations intersect?

Back

Set the equations equal to each other and solve for x, then substitute back to find y.

Front

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

Back

The slope of the line is 3.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line is decreasing from left to right.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.

Front

How do you determine if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
