Question

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes.

y= 1 3 x− 2 3

Answer 1

to find the y-intercept, set x=0 and solve for y:
y= 13(0)-23 = -23. so the point is (0,-23)

to fold the x-intercept, set y=0 and solve for x:
0=13x-23 -> 23/13 =x. so the point is (23/13,0)
