Answer:
10
Step-by-step explanation:
4=2/5 8=4/5 10=5/5
By process of elimination. 3y and -3y get eliminated. Giving you
3x=18
Divide by 3 on each side
Giving you x=6
Plugging it into equation 2 you get
(6)-3y=3
Taking out the parenthesis you have
6-3y=3
Subtract by 6 on each side giving you
-3y=-3
Divide by -3 on each side giving you
y=1
So the answer for this equation is x=6 and y=1 or the ordered pair (6,1)
Answer:
<em>Equation; y = - x + 3</em>
Step-by-step explanation:
To determine the equation, let us first determine the slope of the line, through the equation ( y2 - y1 ) / ( x2 - x1 ), in this case where y2 ⇒ 1, y1 ⇒ 5, x2 ⇒ 2, and x1 ⇒ -2;
( 1 - 5 ) / ( 2 - ( - 2 ) ) ⇒ Simplify,
( - 4 ) / ( 4 ),
<em>Slope; - 1</em>
Now that we have the slope, let us substitute this known value into the point - slope equation in the following form;
y = a * x + b, where a ⇒ slope, and b ⇒ y - intercept,
( So far we have ) y = - x + b,
Let us solve for the value of b in y = - x + b by substituting one of the points, say ( 2 , 1 ) where x ⇒ 2, and y ⇒ 1;
( 1 ) = - ( 2 ) + b,
1 = - 2 + b,
b = 3;
<em>Equation; y = - x + 3</em>
