give the slope of a line perpendicular to the given line?

Question

y= -3x + 9

Answer 1

If I remember correctly, it's the negative inverse of the given line. In the equation y=mx+b, m= slope. So in your equation, the perpendicular line would have a slope of +1/3.

Answer 2

The slope of your line is -3x. The slop of the perpendicular line is the different and reciprocal. this signifies that you multiply it by technique of -a million and that you position it in a fragment with a million on the suitable. So.... -3x will grow to be +a million/3x sources: 10 years of math preparation it really is now a sophisticated calc type. replace: definite. you may merely placed the slope as a million/3

Answer 3

The key word in this problem is "perpendicular."

Graph the equation you have by hand, on your calculator, etc. to visualize the problem. We need to know what the slope of a line perpendicular to this line is.

Here's the bit of info you need to solve the problem: a slope perpendicular to a given slope is the "opposite reciprocal." By opposite, I mean change the sign (+ or -) and by reciprocal I mean one over the initial slope.

If "m" is the slope, then the perpendicular slope is:

-1/m

(Negative one over the slope)

Answer 4

the slope of a line perpendicular to the line y=mx+c
will be the negative inverse of m=>-1/m
applying it here slope of the perpendicular line=-(1/-3)=1/3

Answer 5

1/3
Because the slope of a perpendicular is the negative reciprocal of the slope of the given line.
since the linear equation has the form y = mx + b, m = -3, the slope.

Answer 6

y=1/3+9

perpendicular line flips the m (y=mx+b) and places the opposite sign of m from the original eqation.

y=mx+b

Y=-3+9

y=1/3+9

(The b from y=mx+b can be any number positive or negative. It is just the starting point for the slope of your line)

Answer 7

Slope of the given line = -3
Angle that it makes with x-axis = tan inverse(-3) = -71.565 deg.
Angle of the line perpendicular to it = -71.565+ 90 = 18.435 deg.
Slope of this line = tan(14.435 deg) = 0.333

Or more simply m*m' = -1, where m and m' are the slopes of two mutually perpendicular lines; so m' = -1/m

Answer 8

1/3, simple, or from the origin of the cartesian plane count 1 unit to right and and 3 units up. Slope is dx/dy remember.

Answer 9

What are you, like 13? I learned that in 7th grade. I mean, the given equation is even in basic form. C'mon, you can't make it difficult, like 107y = 323646x -55?
