Answer:

Plot the point (3, -5)

Step-by-step explanation:

Recall that the general number a+bi can be plotted on a complex plane with the x axis as the real part and the y axis as the imaginary part.

In short,

a = real part = x

b = imaginary part = y

So (a,b) = (x,y)

In this case, a = 3 and b = -5 which is how I got (3, -5).

It might help to rewrite 3 - 5i into 3 + (-5)i

a system of equations is graphed here. which system of equations does the graph represent? A) y = 3x + 2y = -2x + 5 B) y = 3x -

n200080 [17]

Notice that the line with negative slope has a y-intercept of 5 and the line with positive slope has a y-intercept of 2.

On the other hand, the slope of the line with negative slope is -2, while the slope of the line with positive slope is 3 (This can be identified since in one case, the value of y decreases by 2 for each increase of 1 unit in x, and in the other, the value of y increases by 3 for each increase of 1 unit in x).

Using the y-intercept form to represent each line, the system of equations represented by the graph must be equivalent to:
