Answer:
The input is 1/7
Step-by-step explanation:
If y =f(x)
Given that f(x) = -7x -2, then y = -7x-2
x is the input
y is the output
Given the output y = -3, we are to find the input value x
Recall that y = -7x-2
On substituting the value of y into the equation
-3 = -7x - 2
-7x = -3+2
-7x = -1
x = -1/-7
x = 1/7
Hence the input is 1/7
<span>5y = 10x - 15
y = -5x - 3
so slope = -5
x - intercept when y = 0
</span> -5x - 3 = 0
-5x = 3
x = -3/5
(-3/5, 0)
y - intercept when x = 0 then y = -3 (0,-3)
answer
slope = -5
x-intercept (-3/5, 0)
y-intercept (0, -3)
A) No, because 62 + 9 = 122
