Answer:

Yes but there is only one way to check they are an ordered pair.

This is done by using simultaneous equations

ascending line is  y = 2x + 9

descending line is  y = -2x + 7

The ordered coordinates can be checked ( -4, 1)

2 (-4) + 9(1) = 1

and

-2 (4) +7 (1) =  -1

Use the information given to enter an equation in standard form.
Kruka [31]

Answer:

y=1.6x-8.4

Step-by-step explanation:

First, find the slope which is  y 2 minus y 1 divided by x 2 minus x 1

Slope= 16/10 or 1.6

So now it is y=16/10x + b or y=1.6x+b

Now pick a random coordinate and substitute to find y intercept we can use the first one (29,38)

38=1.6(29)+b

y intercept = -8.4

Equation is y=1.6x - 8.4 or y=16/10x - 8.4

Hoped this helped :)

the difference between two numbers is 342. the bigger number is 4 times the smaller number. find the product of the two numbers.
SVETLANKA909090 [29]

Let the two numbers be x and y.

x = 4y

x - y = 342

3y = 342

y = 114

xy = 4y * y = 456 * 114 = 51984

Write the expression in WORDS!<br><br> 5x + 3
Svet_ta [14]
The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!
