It’s very simple in every line you need slope and y-intercept so you use,
y=Mx+c (M is slope and c is y-intercept)
First find slope and use any two points on the line I prefer picking (-3,0) and (0,2)
= y2-y1/x2-x1 = 2-0/0-(-3) = 2/3
Y=2/3x+c (now last step we find c by replacing any of the giving points)
2=2/3(0)+c
C= 2
Final answer :
Y=2/3x+2
