Hm...
What's the problem Jeffrey?

Nothing really, I just have a problem
And what is that problem?

It's the news they say that the people got infected by COVID-19 is around 3x+2y=10
To solve 3𝑥+2𝑦=103x+2y=10 for 𝑦y, subtract 3𝑥3x from both sides to isolate 𝑦y, giving 2𝑦=10−3𝑥2y=10−3x. Then, divide both sides by 22 to get 𝑦=5−32𝑥y=5−23x, which is in slope-intercept form 𝑦=𝑚𝑥+𝑏y=mx+b, where 𝑚m is the slope and 𝑏b is the y-intercept. Therefore, the slope is −32−23 and the y-intercept is 55.

So that means every data is always collected on how much people have been affected by the virus?
To solve for 𝑦y in 4𝑥−5𝑦=154x−5y=15, first, subtract 4𝑥4x from both sides to isolate 𝑦y, yielding −5𝑦=15−4𝑥−5y=15−4x. Then, divide both sides by −5−5 to get 𝑦=−3+45𝑥y=−3+54x. This equation represents a line with a slope of 4554 and a y-intercept of −3−3

Good Luck on your test tomorrow!!
Wow you taught me a lot of linear equations. I have a feeling that I might perfect my test.
Slidkalniņš: 6
How was the test? Did you perfect it?
Ya. Thanks for helping me Brennan! Now I know the value of the data that has given to us!
