Answer:

Hello,

First equation is false

Second equation is true

Step-by-step explanation:

(4,-3) is a point of the line y=4x-19 since

-3=?4*4-19

-3=-3

(4,-3) is not a point of the line y=1/4x-2 since

-3=? 1/4*4-2

-3=? 1-2

-3≠-1

I have written that because it is difficult for me to understand

"the negative reciprocal of the slope of the first"

the negative reciprocal of 4 should be -1/4.

Equation y=1/4x-2 is false.
