Which of the following equations has a maximum at (9,7)? A. y = -x2 + 14x − 40 B. y = -x2 + 18x − 74 C. y = -x2 − 14x − 58 D. y = -x2 − 18x − 88 WILL MARK BRAINLIEST

B is your answer :)

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
