Answer:
The Answer is: y = 2x - 3
Step-by-step explanation:
Given points: (3, 3) and (4, 5)
Find the slope, m:
m = y - y1/(x - x1)
m = 3 - 5/(3 - 4)
m = -2/-1 = 2
Use the Point Slope form of the equation:
y - y1 = m(x - x1)
y - 5 = 2(x - 4)
y - 5 = 2x - 8
y = 2x - 8 + 5
y = 2x - 3
Proof:
f(3) = 2(3) - 3
= 6 - 3 = 3, giving (3, 3)
Answer:
Step-by-step explanation:
Solve by doing y-y1 Over
x-x1 to find m. Pick either set of points and set up the equation as y=mx+b. So if you were to pick 3,3 as your set of points you would set up the equation like this: 3=m(that’s what you find earlier in the problem) (3) +b. Hope this helps in not good at explaining
