Answer:
The answer is y=-x+9.
The first thing to do is find where the line intercepts the y-axis, which is at positive 9 so you'll add a +9 to the end of your equation. Next you find the slope and since it's going down left to right, you know it is a negative. Now slope is found by change in y divided by change in x. And since both change and y and change in x are both 1, 1/1 is 1. And since you know it's negative that means the slope is -x. Altogether you get y= -x+9
The 3.1 °F/min rate of change of the temperature and 15 minutes change duration gives the change in temperature as 46.5 °F
<h3>How can the change in temperature be found from the rate of change?</h3>
The rate at which the temperature changed = 3.1 °F/min
The duration of the change in temperature = 15 minutes
The relationship between the change in temperature, the rate of change in temperature and the time can be presented as follows;

Where;
∆T = The required change in temperature
∆t = The duration of the change = 15 minutes
Which gives;
∆T = 3.1°F/min × 15 minutes = 46.5 °F
- The change in temperature, ∆T = 46.5 °F

Answer:
Y = 6 X=-1
Step-by-step explanation:
- Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
- So that means 6y=36. So Y would equal 6
- Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
- Minus 22 from both sides.
- That would give you 8x=-8
- So x would equal - 1
Then the number must be between 18² = 324 and 19² = 361. But is that what you want to know?
