Answer:

Explanation:
The correct question is
Find the output, k, when the input, t, is -7 . k = 10t-19
we have

This is a linear equation in slope intercept form
where
k is the output value
t is the input value
The slope is

The y-intercept (or k-intercept in this problem) is

To find out the value of k, substitute the value of t in the given equation
so
For t=-7
