Write a function equation that represents a line that contains the two points (-3, 5) and (2, 10).
Eva8 [605]

Step-by-step explanation:

1. 1st of all calculate the gradient

( - 3, 5) ( 2, 10)

Gradient = (10 - 5) / ( 2--3)

= 1

2. Then find the eq

Y = mx + c

Where m is the gradient

y= 1x + c

Now replace any 2 coordinates from above in the eq.

For ex I'm taking (2, 10)

Y = 1x + c

In the coordinate, x = 2 and y =10

By replacing this in the eq, I will find c

10 = 1(2) + c

2 + c = 10

c = 10 - 2

= 8

So the eq is y = x + 8 ⬅️

Justine and Meagan played a trivia game. Justine answered a question incorrectly and lost 7 points. Then Meagan answered correct
Nataliya [291]

Answer:

m = -j, or in this case, m=-(-7)

Step-by-step explanation:

Assuming that Justine's score is represented by j and Meagan's score is represented by m, we know that j will always be the opposite of m.

To represent opposite, we put a negative sign before the variable.

This makes the current number, even if it's negative, the opposite value.

Let's test it out.

Since Justine's score is -7, substituting it into the equation makes it  m=-(-7). We know that two negatives make a positive, so m=7.

Now let's assume Justine's score is 7. Plugging it into the equation, we get m=-(7). That's the same thing as m = -1(7), and -1 times 7 is -7.

Hope this helped!
