Question

Can someone explain this in the easiest way possible.

Answer 1

i give up

Answer 2

Well.

Here's the easy way out: https://www.desmos.com/calculator

My teacher's recommend it..

Answer 3

You gotta put 'em in the form of \(y = mx + b\).

Answer 4

An easy way out is to use logical deduction --> from the graph, the y intercept is 5, therefore the y must be positive. With that, A is definitely the correct answer.

Answer 5

Answer 6

Okay. thank you

Answer 7

Excellent way of putting it.

Answer 8

thanks ^.^

Answer 9

To find the equation, we must first find key values.
y=mx+b
That is the slope and y intercept.
The y intercept is the value of y when x equals 0, so we can see here it's 5.
b=5

The slope can be found simply by finding the change in y over the change in x from a perfect point. two points I can see are (0,5) and (9,0). Count the units down, it is 5 units or -5. The units across is 9. So, the slope is -5/9.
m=5/9.

All you have to do now is convert y=-5/9x+5 to standard form which is ax+by=c. Basically, solve for the constant.

Answer 10

@quietus That does not eliminate option B, unless you go and get the x-intercept too.

Answer 11

Sorry, I meant to put m=-5/9

Answer 12

ahh, yes, @agent0smith , but when you see -x, you would know its incorrect as x = 9 on the graph

Answer 13

You would, but how do you know that she would...?

Answer 14

er.... im sry :3 as long as she puts in the y = mx + b format it'll be great
