-5 times -8 = 40
That should be right because a negative times a negative equals a positive

Answer:

The answer to your question is:         y = -2x + 10

Step-by-step explanation:

Data

Point = (1, 8)

Line    y = x/2 + 3

perpendicular

slope = 1/2  but the lines are perpendicular, then slope = -2

Equation

                    ( y - y1) = m ( x - x1)

                     (y - 8) = -2(x  - 1)

                     y - 8 = -2 x + 2

                     y = -2x + 2 + 8

                    y = -2x + 10

Help asap plz math isn't my thing​

<h3>✽ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ✽</h3>

➷ We have 2 points which we can use to figure out the slope

slope = difference in y values/ difference in x values

Substitute in the values you have:

0 - 5/ 3 - 0

slope = -5/3

The y intercept is simply where the line crosses the y axis

In this case, it is 5

Therefore, your equation is y = -5/3x + 5

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

Two functions are defined as shown.
maxonik [38]

Answer:

Graph (2).

Step-by-step explanation:

Given question is incomplete: Find the complete question in the attachment.

Given : f(x) = -\frac{1}{2}x-2

            g(x) = - 1

To find : The graph showing f(x) = g(x)

If the given functions f(x) = g(x)

-\frac{1}{2}x-2=-1

-\frac{1}{2}x=-1+2

-\frac{1}{2}x = 1

x = -2

That means both the functions have the same value at x = -2

f(-2) = g(-2) = -1

In other words, both the lines will intersect at a point (-2, -1).

From the given graphs,

Graph number (2) shows the required results.

A straight line g(x) = -1 parallel to x- axis and another straight line f(x) = -\frac{1}{2}x-2, intersect each other at (-2, -1).

Therefore, Graph (2) will be the answer.
