Writing an Equation from a Graph y = mx + b

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0, represented by b in the equation.

Front

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

Back

The letter 'm' represents the slope of the line.

Front

How do you find the slope from the equation y = mx + b?

Back

The slope is the coefficient of x, which is 'm'.

Front

What is the slope of the line in the equation y = 2x + 3?

Back

The slope is 2.

Front

What is the equation of a line with a slope of 4 and a y-intercept of 3?

Back

The equation is y = 4x + 3.

Front

How do you write the equation of a line given a slope and a point?

Back

Use the point-slope form: y - y1 = m(x - x1).

Front

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

Back

The slope is -3/4.

Front

What does the term 'slope' indicate about a line?

Back

The slope indicates the steepness and direction of the line.

Front

If a line has a positive slope, what does that tell you about its direction?

Back

The line rises from left to right.

Front

If a line has a negative slope, what does that tell you about its direction?

Back

The line falls from left to right.
