a= 1/2bh
=1/2(10)(5)
=1/2(50)
1. the equation is y=mx+b. m= slope and b= y-intercept so your answer should be y=2/3x+2
2. point-slope form is y-y1/x-x1=m answer is y+4=-1(x-1)
3. i give up im sorry my brain is fried ;-;
4.uhh i graphed it and attached an image lol
dang i- cant do no more math today lol sorry good luck
