Question

What is the y-intercept of the line described by the equation below?

y = 7x + 4

Answer 1

The y-intercept is where the graph crosses the y-axis. In the equation y=mx+b, the y-intercept is the b. So in y=7x+4, the y-intercept would be positive 4, or the ordered pair (0,4).

Answer 2

The y-intercept is 4.

What is linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

GIven equation,

y = 7x+4  

Comparing to the equation of Line y=mx+b,

Whereas the y-intercept is the b.

So, 7 is the slope and 4 is the y-intercept

Hence the y-intercept is 4.
