With great difficulty because without an equality sign the given terms can't be considered to be an equation but if you mean y = 14.2-3.9x then the y intercept is 14.2

The y-intercept of a linear equation is the point where the graph of the line represented by that equation crosses the y-axis.
The slope-intercept form of a linear equation is y = mx + b where m = slope and b = the y-intercept.
It could be any value
A Y-intercept and the slope. The y-intercept is where the line crosses the Y axis.
The y-intercept of a linear equation is the point on the y-axis at which the line cuts.It could be found by plugging x = 0 in the given linear equation.For example,Consider 3x + 2y = 6. To find the y-intercept just plug x = 0 in the equation.3(0) + 2y = 62y = 6y = 3(0, 3) is the y-intercept of the linear equation 2x + 3y = 6.Note:In the same way we can find the x-intercept by plugging y = 0 in the given linear equation.
