The graph y = x squared - 3x + 4 is plotting on to a set of axes. What are the co-ordinates of where the graph crosses? A). 1,4

B). 4,1

C). 4,0

D). 0,4

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
