Question

The equation of a line is y = 4x + 15. what is the y-intercept of the line.

Answer 1

15

Explanation:

`y = 4x + 15 \\ equating \: it \: with \\ y = mx + b \\ we \: find \\ b = 15 \\ \implies \: y - intercept = 15`

Answer 2

Y intercept = 15

Explanation:

Formula we use,

→ y = mx + b

→ b = y intercept

Then the y intercept will be,

→ y = mx + b

→ y = 4x + 15

→ [ b = 15 ]

Thus, required answer is 15.
