Answer:
x -y = -5
3x +y = -11
Step-by-step explanation:
We assume you want two linear equations. Since you know a point on each line, the only thing you need to choose is the slope of the two lines through that point. We can make the slopes be +1 and -3, for example. Then the point-slope equations are ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -1 = +1(x +4)
y -1 = -3(x +4)
We can use these equations "as is", or put them in whatever form you like. I personally prefer "standard form:" ax+by=c.
<u>First equation</u>:
y -1 = x +4 . . . . . . eliminate parentheses
-5 = x -y . . . . . . . keep positive x term, put x and y together, separate from the constant
x - y = -5 . . . . . . standard form
<u>Second equation</u>:
y -1 = -3x -12 . . . . eliminate parentheses
3x +y = -11 . . . . . . add 3x+1 to both sides

A system of equations with solution (-4, 1) is ...
- x - y = -5
- 3x + y = -11
First we shall convert those millions to complete number.
We know 1 million is 1,000,000
So 134.8 millions shall be
= 134.8 × 1,000,000
= 134,800,000
Now we shall convert this to the standard form.
As there are 8 digits after 1, we shall have 8 as the exponent of 10 in the standard form
So
134,800,000
= 1.348 ×
134.8 million in standard form is 1.348 ×
