Answer:
Plot[-1 + 3^Surd[x, 3], {x, -20, 28}]
<span>One pair of metric unit of length would be meters and kilometers. 1 km is equal to 1000 meters. Metric system is the official/standard in measuring length, mass, area, volume, speed, etc. and it is the agreed system of measurement.</span>
The line crosses the y-axis at y=4, so will have an equation of the form
... y = (something)·x + 4
The line rises from left to right, so has a positive slope. That is, the "(something)" must be greater than zero.
The only selection that meets these criteria is
... B y = 2x + 4
