Plot the following two lines: Y = 35 – X and Y = 5 + 2X Find the point where the two lines intersect each other, and find the points of intersection with the x and y axes. Solution: To plot the lines, select a value for x and solve the equation for y to yield point (x,y). Repeat the process to find another point, and draw a line through the two points. NOTE: These are linear equations (equations representing straight lines) in the form of Y= b + mX , where b is the y-intercept and m is the slope of the line. Ex: Let X = 1; then Y = 35 – 1; Y = 34; (X,Y) : (1, 34) (A) and Let X = 20; then Y = 35 – 20; Y = 15; (X,Y) : (20, 15) (B) The line Y = 35 – X passes through points (1, 34) and (20, 15). Let X = 1; then Y = 5 + 2(1); Y = 7 (X,Y) : (1, 7) (C) Let X = 20; then Y = 5 + 2(20); Y = 45 (X,Y) : (20, 45) (D) The line Y = 5 + 2X passes through points (1, 7) and (20, 45) NOTE: It is often easiest to plug 0 in for x and then for y, but the above example shows that this technique will work with any values you choose.
