5x = 4y - 3

The correct answer is D. 5x - 4y = -3

This is because standard form is the form ax + by = c, where a, b, and c are coefficients or constants of the variables x and y. Thus, Answer D (above) is the correct answer to this problem, as it is the only option that fits this.

Please helppp 15 pointsss What is the y-coordinate of the solution for the system of equations?

Lina20 [59]

y = 3x - 1

x - y = -9

Subs y in second equation.

x - (3x - 1) = -9

x - 3x + 1 = -9

-2x = -9 - 1

-2x = -10

x = -10/-2

x = 5

Subs x

y = 3x - 1

y = 3.5 - 1

y = 15 - 1

y = 14

Find the slope of a line that passes through the given points. Write your answer below.

12345 [234]

Just use the formula:
$slope(m) = \frac{y_2-y_1}{x_2-x_1}$

Then, plug in numbers:
$m = \frac{1-4}{-2-3} = \frac{-3}{-5} = \frac{3}{5}$

And that would be your answer: 3/5 is the slope.
