Answer:
y = x - 2
Step-by-step explanation:
The equation of a line can be known as y = mx + b, with m being the slope and b being the y intercept.
1. Find the Slope
The slope can be known as the change in y/change in x.
Two points: (2,0), (0,-2)
-2 - 0/ 0 - 2 = -2/-2 = 1
Slope is 1
So now we can replace the m as 1. So that is y = x + b
2. Find the y intercept
The y intercept is -2 because that is the point where the line meets the y axis.
So our equation is y = x-2

The speed 217 miles per hour using dimensional analysis to convert to feet per minute is; 19096 ft/min
<h3>How to use Dimensional Analysis?</h3>
From dimensional analysis, we know that;
1 mile = 5280 feet
1 hour = 60 minutes
Thus;
1 mile/hr = 88 feet/min
Since conversion from mph to ft/min is, 1 mile/hr = 88 feet/min
Then, 217 mile/hr = (217 mile/hr/1 mile/hr) * 88 feet/min
⇒ 19096 ft/min

I don't know if this is the equation you need. But here it is.
Y - 4 = -2 (x + 1)
Answer:
57971014.49 Hz or 5.79 * 10^7 Hz
Step-by-step explanation:
Given that:
Speed of microwave (v) = 2,000,000 m/s
Wavelength, λ = 0.0345 m
Frequency :?
Using the relation :
v = fλ
f = v / λ
f = 2,000,000 / 0.0345
f = 57971014.49 Hz
