Respuesta :
Y- intercept for the line y = 5x is 0. This can be get from the standard equation for a line.
For the The standard equation for a line is,
y = ax + b
y is called the dependent variable because its value depends on the value of x
a is the slope of the line
x is called the independent variable because it can be any value
b is the y-intercept
Here y is a function of x. You could simply write it as y = 5x. Thus if we compare to the standard form equation y = ax + b, a=5 and b=0. Thus the y-intercept is zero. The reason that this is the case is that when you set x=0 the value is plotted on the y axis because the equation for the y axis is the line defined by x=0. Any value in the x, y plane where x is equal to zero plots on the vertical line going through (0,0) or in other words the y axis.
