First we need slope


Put D co-ordinates on y=mx+b




Now
slope intercept form.

Answer:
x + 3
Step-by-step explanation:
When you substitute the x for -3, it will equal 0. This means it's a zero of the function.
2/15+3/15=5/15 5 can go into both 5/5=1 and 15/5=3 which means
=1/3 is the answer
-201+189=-12-201=-213+189=-24 . S the sign would be negative(-).
