correct me if I'm wrong please.

7. what is the equation of the line which passes through c(2,3) and has a slope m =1/2?
a.)x-2y=-4 <<<<< my choice
b.)2x-y =1
c.)2x+y=7
d.)x+2y=8

what is the equation of the line which passes through point d(-4,2) and has angle of inclination 0=60degrees? leave all decimal places in the result.

a.)0.8660x-y=-5.46412
b.)1.73205x-y = -8.9282 <<<
c.)x - 0.86603y =5.73206
d.) x -1.73205y = -7.4641
