Simplify the expression -5+i/2i Can someone please explain this to me!

1 answer:

5 0

Think of it as -5+1i/2i, since 1i=i. From there, the i's could cancel out since dividing a number by itself would just equal 1. It would then be -5+1/2 which would be simplified to -4 1/2. No need to worry about those i's at all!

Write the equation in POINT-SLOPE FORM of the line that passes throught (5,9) and has a slope of -7.

Debora [2.8K]

Answer:

The equation of line with slope -7 passing through (5,9) in point-slope form is:

$y-9 = -7(x-5)$

Step-by-step explanation:

Given

Slope of line = m = -7

Point = (5,9)

The point slope form of equation is obtained from a point and slope. It is given by the equation:

$y-y_1 = m(x-x_1)$

We know that (x1,y1) = (5,9)

Putting the values we get

$y-9 = -7(x-5)$

Hence,

The equation of line with slope -7 passing through (5,9) in point-slope form is:

$y-9 = -7(x-5)$
