F(x)=-2x
Explanation:
there’s no y-int cuz y-value is 0 when x-value is 0. So u can just ignore that
So you want the slope, rise/run so 2/1 but it’s negative so -2.
Let x = first number, and y = second number.
x + y = 40 (1)
x - y = 6.5 (2)
Rearrange (2)
y = x - 6.5 (3)
Sub (3) in (1)
x + (x - 6.5) = 40
2x - 6.5 = 40
2x = 33.5
x = 16.75 (4)
Sub (4) in (1)
16.75 + y =40
y = 23.25
x * y = 16.75 * 13.25 = 221.9375
The product is 221.9375
