. Write an equation that is perpendicular to y=2x – 1 and has y-intercept of -3
blagie [28]

The answer is very simple .

First you need to determine the slope, which is the reciprocal of the first line.

Then,

y = mx + b

m => -1/m

The perperdicular line has a new slope equal to m = -1/2

In the formula (y - y1) = m ( x - x1 ) + b , you should sustitude this value.

So the final equation will be

-3 = -1/2 (0) + b

b = - 3

y = (-1/2)x - 3

That is the solution

What is the unit distance, Rounded to the nearest hundredth, between the points (-5, 2) and (3, 7)?
Lostsunrise [7]

Answer:

Distance=9.43 units

Step-by-step explanation:

When you have two coordinates and you need to find the distance between them, you can use the distance formula.

D=sqrt(7-2)^2+(3-(-5))^2

D=sqrt(5^2+8^2)

D=sqrt(25+64)

D=sqrt89

D=9.43, rounded to the nearest hundredth.

Therefore, your distance would be 9.43 units.

I hope this helped! Have a good rest of your day~
