Y= 2x - 3
y= -x + 9

graph the solution

Y = 2x - 3
y = -x+ 9

2x-3 = -x+9
2x+x = 9+2
3x = 12
x = 12/3
x = 4

y = 2(4)-3
y = 8-3 = 5

Mark on (4,5) & draw the line from origin.

Hope this helps!

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
