Answer:

Ordered pair: (3,1)

Step-by-step explanation:

Given: System of equation

2a - 5b = 1 and 3a + 5b = 14

Using elimination method.

In this method, we make same coefficient of any one variable and cancel it.

2a - 5b = 1

3a + 5b = 14

We make coefficient of a same.

2a - 5b = 1 ( Multiply by 3)

6a - 15b = 3

3a + 5b = 14 (Multiply by -2)

-6a - 10b = -28

Add both equation

6a - 15b = 3

-6a - 10b = -28

-25b = -25

b = 1

Put b=1 into 2a - 5b = 1

2a - 5(1) = 1

2a = 6

a = 3

Solution: a=3 and b=1

Ordered pair: (3,1)

Hence, The Ordered pair (3,1) is a solution to the given system of equation.

Write the slope-intercept form of the equation of each line.

gregori [183]

Greetings!

Answer:

2y = x - 6

Step-by-step explanation:

First, we must find the slope of the current equation.

This is the number in front of the x.

Seeing as this is -2x, the slope of this line is -2

When finding the slope of a line perpendicular, you need to find the $\frac{-1}{slope}$

So, in this case it is:

$\frac{-1}{-2}$

The negatives cancel out which leave $\frac{1}{2}$

So the gradient is $\frac{1}{2}$

Now, to find the equation of a line, you need to use:

y - y1 = m(x - x1)

Where ya and x1 are the values in the coordinates (2 , -2)

So y1 = -2, x1 = 2, and m is a half. Plug these values in:

y - - 2 = $\frac{1}{2}(x - 2)$

We need to get rid of the half so we multiply the whole equation by 2:

2y - - 4 = (x - 2)

The minus and the negative turn into a positive:

2y + 4 = x - 2

And now simply move the +4 over to the other side, making it a negative:

2y = -2 - 4 + x

Simplify:

2y = x - 6

<h3>So the equation of the line is 2y = x - 6</h3>
<h2>Hope this helps!</h2>
