Finding Slope & Y-Intercept from Graphs & Tables

Front

What is the coordinate for the y-intercept?

Back

(0, 0) is the coordinate for the y-intercept, where the line crosses the y-axis.

Front

How do you find the slope from two points?

Back

Slope (m) = (y2 - y1) / (x2 - x1). It represents the steepness of the line.

Front

What is the formula for finding the slope from a graph?

Back

Identify two points on the line, then use the slope formula: m = (rise/run).

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the y-intercept of a line?

Back

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

Front

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

Back

Set y = 0 in the equation and solve for x to find the x-intercept.

Front

What is the x-intercept of the equation 4x - 10y = 20?

Back

The x-intercept is 5, found by setting y = 0 and solving for x.

Front

What is the y-intercept of the equation 4x - 10y = 20?

Back

The y-intercept is -2, found by setting x = 0 and solving for y.

Front

How can you find the slope from a table of values?

Back

Calculate the change in y over the change in x between two points.
