Step-by-step explanation:
Answer: x = 7
Step-by-step explanation:
2x - 6 = 8x - 48
+48
2x + 42 = 8x
-2x
42 = 6x
/6
7 = x
Multiply the two as area is base times height.
Answer:
y = 
Step-by-step explanation:
We are given the point (3, 10).
The second point is 2 on the x-axis and -7 on the y-axis. So our second point is: (3 + 2, 10 - 7) which is (5, 3).
Our formula for slope is m =
= 
So, our equation would be
= 
Using the standard formula of a line, y = mx + b, we can substitute for the slope, m.
y =
+ b
Now, we can substitute a point on the line to determine the y-intercept:
Using the point (3, 10),
10 =
+ b
b = 10 + 
b = 
So our full equation is: y =
