<span>m = j + 16
m + 5 = 3j
---
put the system of linear equations into standard form
---
m - j = 16
m - 3j = -5
---
x - y = 16
x - 3y = -5

so now that you have your equations formed, just solve.

x - y = 16 , which means that x = y + 16
substitute for x in the second equation :

Hope this helps

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

RUDIKE [14]

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
