Question

It says write an equation of the line shown and the line goes through points 4,3 and 1,-3

Answer 1

Slope of the line;
slope=$\frac{change in y}{change in x}$
Slope=$\frac{3--3}{4-1}$
Slope,m =$\frac{6}{3} =2$
y=mx+c
y=2x+c
Replacing for x and y using point (4,3)
3=2(4)+c
3=8+c
c=3-8
c=-5
y=2x-5
