Writing Slope Intercept Equations (given slope and y-int.)

Front

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

Back

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

If a line has a slope of -2 and passes through the point (3, 5), what is the equation of the line?

Back

Using the point-slope form, the equation is y - 5 = -2(x - 3), which simplifies to y = -2x + 11.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.
