find y intercept

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, y).

Front

How do you find the y-intercept from an equation?

Back

To find the y-intercept from an equation in the form y = mx + b, set x = 0. The value of y at this point is the y-intercept.

Front

What is the y-intercept of the equation y = -2x + 5?

Back

The y-intercept is 5, represented as (0, 5).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

Front

If a line has a y-intercept of (0, 3), what does this mean?

Back

It means that the line crosses the y-axis at the point (0, 3).

Front

How can you determine the slope from two points on a line?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What is the y-intercept of the equation y = 3x + 2?

Back

The y-intercept is 2, represented as (0, 2).

Front

What is the significance of the y-intercept in real-world scenarios?

Back

The y-intercept can represent the starting value of a situation, such as initial cost or starting population.

Front

If the y-intercept is (0, 7), what is the value of y when x = 0?

Back

The value of y is 7 when x = 0.
