The equation format for a straight line is y = mx + b, where m is the slope and b is the y-intercept, the value of y at x = 0. The slope is the rate of change of the line as x changes values. It is also termed the "rise over the run," of the difference in the value of y as x is changed.
We can calculate the rise/run from the two points. (0,2) and (-4,5). The rise is the difference between the two y values (5 - 2 = 3) and the run the difference in the x values (-4 - 0 = -4). Rise/run is therefore -3/4. This is "m" in the equation.
y = -(3/4)x + b
We need to find b. Input one of the points, (0,2) and solve for b.
2 = -(3/4)*0 + b
b = 2 (the line crosses the y axis when x = 0).
The full equation becomes:
y = -(3/4)x + 2
O(30) is the 30th odd number as well as 2(30) - 1 = 60 - 1 = 59
A and D are correct.
The length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.
<h3>What is an ampere circuit?</h3>
Ampere's circuital law states that “the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.”
Here we have a cable rating of 120-volt/15-amp so if the 1-ampere circuit means 1 watt per foot cable will be used for the 1-ampere circuit.
A Total of the 15-ampere circuit means 15 watts needed so we are using 2.5 watts per foot.
Hence the length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.
