Complete the solution of the equation. find the value of y when x equals 1. <br><br>9x +7y= -12

Taya2010 [7]

Answer:

$y=-3$

Step-by-step explanation:

Given Equation:

$9x +7y=-12\\$ y=? at x= 1

Putting the given value of 'x' in the equation:

$9(1) +7y=-12\\\\9+7y=-12\\\\7y=-12-9\\\\7y=-21\\\\y=-\frac{21}{7} \\y=-3$

At $x=1$ , the value of y is $y=-3$

What is the slope of the line whose equation is -48 = 2x - 8y?<br> Enter your answer in the box.

aleksandr82 [10.1K]

Answer:

The slope is $\frac{2}{8}$

Step-by-step explanation:

Take the general equation of a straight line $y = mx+c$

Here $m$ is the slope of the line.

So let's get the equation of the line in the question in the same form.

$-48 = 2x-8y$

Add $8y$ to both sides: $8y - 48 = 2x$

Add $48$ to both sides: $8y = 2x + 48$

Divide by $8$ to get it into the general equation: $y = \frac{2}{8} x + 6$

Now compare it to the general equation to find the value of $m$ . The value of $m$ is the coefficient of $x$ which we can see is $\frac{2}{8}$
