Question

Fill out the other coordinate for the line y=7/2x+6 (-3, )

Answer 1

The coordinate is (-3, -4.5).
If you want to find the answer, x is -3. You can substitute x for -3 in the equation y=(7/2)x+6. The equation will then be y=(-21/2)+6. y will equal to -4.5, giving you the y-coordinate. 

Answer 2

(x,y)
when x=-3 then find y
y=(7/2)(-3)+6
y=(-21/2)+6
y=(-21/2)+(12/2)
y=-9/2
so the other coordinate is -9/2 or (-3,-9/2) or (-3,-4.5)
