Solve this system of linear equations. Separate
the x. and y-values with a comma.
9x = 48 - by
5x = 8 + 6y
Enter the correct answer.

Step-by-step explanation:

The first equation is actually

Given the following System of equations:

You can apply the Elimination method to solve it:

1. In this case you can start by adding both equations.

2. Then you must solve for the variable "x" in order to find its value.

You get:

3. Now, knowing the value of the variable "x", you can substitute it into any original equation.

4. Finally, solve for "y" in order to calculate its value.

You get that this is:

Then the solution in the form , is:

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
