Question

will award metal if right answer

Which line is not perpendicular to the line 4x − 3y = 2?

3x + 4y = 2

3x − 4y = 2

-3x − 4y = 5

3x + 4y = -8

Answer 1

What do you know about the slopes of perpendicular lines?

Answer 2

nothing thats why i put it up there

Answer 3

3 + 3 =9 sooo i think is B

Answer 4

perpendicular lines make a right angle when they intersect

Answer 5

so wats da answer n nice name

Answer 6

The slopes of perpendicular lines are negative reciprocals.
That means that when you multiply together the slopes of two perpendicular lines, you get -1.

Answer 7

Here is the equation of a line in standard form:

\(ax + by = k\)

We solve it for y to get it in slope-intercept form.

\(by = -ax + k\)

\(y = -\dfrac{a}{b}x + \dfrac{k}{b} \)

The slope-intercept form is

\(y = mx + b\), where m is the slope.

That means, to find the slope using the standard form, just find \(-\dfrac{a}{b} \).

Take the given equation and each of the choices, and find \(-\dfrac{a}{b} \).

Then find which choice has a slope that is not the negative reciprocal of the slope of the given equation.
