Slope Intercept Form

SECTION 4.5

What is POINT-SLOPE Form?

What is it used for?

Why is it called point-slope form?

First Example in Video:

Write the equation of a line with a slope of 5 and passing through the point (3, 12) in slope-intercept form and

standard form.

y – y

= m(x – x

)

Point: (__, __)

Slope: ___

How do you handle a slope that has a fraction?

Parallel lines are two lines that do not _______________ in the same plane. The two lines are

_______________ the same _______________ apart. The _______________ of parallel lines are

_______________.

Perpendicular lines are two lines that _______________ at 90 degrees. The two lines seen in the video show

that one has a _______________ slope and one has a _______________ slope. Perpendicular slopes have to

have _______________ signs. The slope of perpendicular lines have negative _______________ or

_______________ reciprocals. So, to find the _______________ slope, you _______________ the fraction over

and _______________ the sign.

The _______________ way to determine if lines are _______________ or perpendicular is to _______________

the slopes.
