Writing Slope Intercept Equations

Front

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

Back

m represents the slope of the line.

Front

What is the slope-intercept form of the equation of a line?

Back

The slope-intercept form is y=mx+b.

Front

What is the equation for the line with a slope of 7 and passes through (0,1)?

Back

The equation is y = 7x + 1.

Front

What is the slope of the line x = -2?

Back

The slope is undefined.

Front

Given that the slope is 2/3 and the y-intercept is -3, what is the equation of the line?

Back

The equation is y=\frac{2}{3}x-3.

Front

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

Back

b represents the y-intercept of the line.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope m is calculated as m = \frac{y2 - y1}{x2 - x1}.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line has a slope of -3, what does this indicate about the line's direction?

Back

The line descends from left to right.
