Question 807729: Find the value of a
A line has slope 3/4 and passes through points (2,3) and (10,a)
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! Get the equation in point-slope form: y - y1 = m(x - x1)
---
using:
m = (3/4)
p1 = (2,3)
p2 = (10,a)
---
y - y1 = m(x - x1)
a - 3 = (3/4)(10 - 2)
a - 3 = (30/4) - (6/4)
a - 3 = (24/4)
a - 3 = 6
---
Answer:
a = 9
