Answer:

Step-by-step explanation:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept(value of x when y = 0).
In this question:
Slope 4, which means that
.
So

Contains point (1,-8).
This means that when
. We replace this into the equation to find b. So



So

Answer:
Isosceles triangle
Step-by-step explanation:
Length of side AB = 
= 
= 
= 
= 4
Length of BC = 
= 
= 
Length of AC = 
= 
= 
Since, AC = BC, ΔABC will be an isosceles triangle.
