Match each equation to equivalent equation. -4x+3y=20 -6x-2y=10. 2x +5y=18

Mathematics
1 answer:
alex41 [277]3 years ago
6 0

Answer:

4x + 10y = 36  ≡  to 2x + 5y = 18

As you can see, the the coefficients on the first one are double those in the second.

12x - 9y = -60  ≡  to -4x + 3y = 20

In this case, the terms in the first one are all the same, but multiplied by -3

And by simple elimination we can say:

-24x - 8y = 40 ≡ -6x - 2y = 10

In this case, the terms of the first equation are equal to those of the latter, but all multiplied by 4.

Plot the line for the equation on the graph. y−4=−1/4(x−5)
icang [17]
You just need two points to graph a line.

When x = 1 

y - 4 = -1/4(1 - 5)
y - 4 = -1/4(-4)
y - 4 = 4/4
y - 4 = 1
y = 5

So, we have our first point, (1,5)

When x = 2

y - 4 = -1/4(2 - 5)
y - 4 = -1/4(-3)
y - 4 = 3/4
y = 4 3/4

Now we have the point (2, 4 3/4)

Now just run a line through the two points and you're done!

Answer:

y = -7/4x - 11

Step-by-step explanation:

formula is y = mx + b

m is the slope

b is the y intercept

y = -7/4x -11

which is the first one
