Answer:
C (- 4, - 2 )
Step-by-step explanation:
(c)
the x- coordinate of A is - 4
the y- coordinate of B is - 2
coordinates of C = (- 4, - 2 )
In exact form that would 2 over 49 and in decimal form that would be 0.04.
Answer:
6=y
Step-by-step explanation:
5y + 6 = -3y +54
isolate y
+3y
8y +6 =54
subtract 6 to isolate y.
8y = 48
divide by 8 so y is alone w no coefficient other than 1
y=6

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>
