Answer: f(x) = 2x + 3
Explanation:
y-intercept at (0, 3)
slope = 2
take the difference between two y-values and divide that by the x-value between them:
5 - 3 / 1 - 0 = 2
Answer:
you can
write this similarly to point slope form, as f(x) is more or less just y, thus the answer would be f(x)=2x+3, because the line rises 2 units and runs one unit, and the line goes through the y at y=3
