Answer:
y=9x-17; x=17/9 or x=1 8/9 or x=1.8
y=x+23; x= -23
Step-by-step explanation:
y=9x-17
0=9x-17 (Move variables to the left-hand side and change its sign)
-9x=-17 (Divide both sides of the equation by -9)
x=17/9, x=1 8/9, or x=1.8
y=x+23
0=x+23 (To find x-intercept/zero, substitute y=0)
-x=23 (Move variable to the left-hand side and change its sign)
x= -23 (Change the signs on both sides of the equation)
x= -23
