Write y=mx+b from graph

Front

What does the equation y=mx+b represent?

Back

It represents the equation of a straight line, where 'm' is the slope and 'b' is the y-intercept.

Front

What is the slope in the equation y=mx+b?

Back

The slope (m) indicates the steepness of the line and the direction it goes (upward or downward).

Front

What does the 'b' in y=mx+b represent?

Back

The 'b' represents the y-intercept, which is the point where the line crosses the y-axis.

Front

How do you find the slope from a graph?

Back

The slope is found by taking the rise (change in y) over the run (change in x) between two points on the line.

Front

If a line goes up from left to right, what can you say about its slope?

Back

The slope is positive.

Front

If a line goes down from left to right, what can you say about its slope?

Back

The slope is negative.

Front

What is the slope of the line represented by the equation y=3x-4?

Back

The slope is 3.

Front

Write the equation of a line with a slope of -2 and a y-intercept of 5.

Back

y = -2x + 5.

Front

What is the y-intercept of the equation y=1/4x + 2?

Back

The y-intercept is 2.

Front

How do you convert a slope-intercept form equation to standard form?

Back

Rearrange the equation to the form Ax + By = C, where A, B, and C are integers.
