Answer:
y - -x + 2.
Step-by-step explanation:
The line passes through (0, 2) and 5, 1) so it slope = (1-2) / (5-0)
= -1 and the y-intercept is at y = 2 so the equation is
B
Answer to your query is provided below in the image attached
using y=mx+c
C=7
y=8
x= -4
we're looking for m
8=-4m +7
1= -4m
m= -1/4
