Finding the x- and y-intercepts may be done either graphically or algebraically. Functions and equations may either be linear or nonlinear. Linear functions are those drawn with a straight line as seen in the illustration below: Graph of y = 2x - 6 with x- and y-intercepts...
Answer: On y-axis, the x-coordinate of the point is 0. Therefore, we can find the intersection point of y-axis and y = 2x + 6 by simply putting the value of x as 0 and finding the value of y. y = 2(0)+6 = 0 + 6 = 6....
