Question

Write the equation of the line that passes through the points (1, 7) and (5, 15) using function notation.

y = 2x + 5

y = 4x + 8

f(x) = 2x + 5

f(x) = 4x + 8

Answer 1

function notion = f(x)
so not A or B

Answer 2

now find the slope
\(\dfrac{15-7}{5-1}=\dfrac{8}{4}=2\)

Answer 3

so C is your answer

Answer 4

Thanks so much, you got yourself a medal :)

Answer 5

your welcome
