Given two points. we can find the equation of a line passing through the points
The formula to be used is:

where


=>

The next step is to cross multiply

=>

Divide both sides by 6 and make x the subject
x=3
Answer:
Rate = 0.7%
Step-by-step explanation:
Rate = Interest / (principal x time)
rate = 12.83 / ((550) x 12/4)
rate = 12.83 / (550 x 3)
rate = 12.83 / 1650
rate = 0.007
rate = 0.7%
Answer:
B) y = 5x
Step-by-step explanation:
We need to find the slope
m = (y2-y1) /(x2-x1)
We have 2 points (0,0) and (6,30)
m = (30-0)/(6-0)
= 30/6
=5
The slope is5
y = mx+b
The y intercept is 0
y = 5x+0
y = 5x
