hellloo !! anybody home ??

Find a & b, substitute back in basic equation i.e y = a +bx.. thats solution for part A ..

Oh sorry i didnt realize anybody answered my question!!

soo.. now u do have solution for part 1.. rt ??

can someone help me with a literature question?

rt ?

oops !! sorry...
right !!

285 = a +3b
510 = a + 6b
is the top equation im suppose to solve for A and bottom B ?

try solving them simultaneously.. u will get values for a & b..

a=3n B=95 right ?

|dw:1385573421916:dw| replace b with it's value and solve for a.

510= a +75 solve this ?

510=a+6*75

a=60

Yes!

how would i write out part A ?

Like @Ganpat said earlier: y=a+bx.

i dont know how to do that

Just replace a and b with their respective values.
