Answer:
Step-by-step explanation:
It is vital to first find the gradient/ slope between the points

let us use the point (6,1) to find the value of c
y=mx+c
1=1(6)+c
1-6=c
∴c=-5
the equation is given by
y=x-5
Answer: x=1
Step-by-step explanation:
When solving for x you must isolate the terms. In order to isolate the terms divide both sides by 3 in order to break up the 3x. that way you should have 2x=x+1 from there i will subtract the x from both sides, so i receive x=1.
