Answer:
k(-7) = = -89
Step-by-step explanation:
k(t) = 10t -19
Let t = -7
k(-7) = 10*-7 -19
= -70-19
= -89
Let’s find the slope and y intercept
Slope: rate of change
Given points (0,5) and (2,0)
Slope: (y2-y1)/(x2-x1)
(0-5)/(2-0) = -5/2
Y intercept = (0,y) = (0,5)
Now into equation: y = mx + b
Y = -5/2x + 5
Get rid of fraction (multiply be 2)
2y = -5x + 10
Add 5x to both sides
2y + 5x = 10
Or 5x + 2y = 10
Solution: D. 5x + 2y = 10

-5 -3 -2 2 3 4
