An investor bought 600 shares of stock, some at $5.00 per share and some at $4.75 per share. if the total cost was $2912.50, how many shares of each stock did the investor buy? (round to two decimal places if necessary.)

m∠a is 90°

m∠b is 40°

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
