Answer:
<em>(1, - 2) </em>
Step-by-step explanation:
2x - y = 4
3x + y = 1
A =
= 2(1) - 3( - 1) =2 + 3 = 5
=
= 4(1) - 1(- 1) = 4 + 1 = 5
=
= 2(1) - 4(3) = 2 - 12 = - 10
<em>x </em>=
=<em> 1</em>
<em>y </em>=
= <em>- 2</em>
<em>(1, - 2)</em>
No, the probability of getting a 5 is 1/6, but you could roll any number of fives in a row. It is just as likely to get rolled the second time as it was the first.
When you're given a point and the slope of a line, it is often easiest to write its equation in
point-slope form.
This is

, where

is the ordered pair for the point you are given and m is the slope.
Here, you would write

. Then, you simplify to get to
slope-intercept form, which is

, where b is the y-intercept.
The correct answer is A.
