x = 0.24
C = hours Carlos drove, M = hours Maria drove.
52*C+54*M = 217
C = 4,1-M
52*(4,1-M)+54M = 217
213,2-52M+54M = 217
217-213,2 = 54M-52M
3,8 = 2M
M = 1,9
Maria drove 1,9h.
Point slope is y-y1= m(x-x1) where m is slope and x1 and y1 are the known coordinates.
y-(-9)=-2(x-10)
y+9=-2(x-10)
Final answer: y+9=-2(x-10)
