Answer:
Altogether, 3 less than 5 times a number is 5n−3 .
Step-by-step explanation:
Draw the triangle and then use Pythagoras' theorem
distance =

= 19.70 (2dp)
(5,-3) (-1,6)
y=mx+b
calculate m:
(-3-6)/(5-(-1)
=-9/6=-1.5
y=-1.5x+b
insert the (5, -3) point to calculate b:
-3=-1.5*5+b
-3=-7.5+b
4.5=b
b=the y intercept, so the line intercepts x=0 at y=4.5
I don't know if this will help but the 2 on the right are not parallelograms there
