In order to calculate the y-intercept of the line described by the equation
y = 5x -22, we have to put x = 0. This is because y-intercept represents the point at which the straight line crosses the y-axis.
If we put x = 0, then 5x becomes 5 x 0 = 0
Therefore, the equation becomes, y = 0 - 22
For this reason, the y-intercept of the line is y = -22.
