The coefficients in the expression are -1 and 9
<h3>How to determine the coefficients?</h3>
The expression is given as:
-x^2 + 9x
In an expression ax, the coefficient is a.
Using the above as a guide, we have:
-x^2 + 9x
The coefficients in the above expression are -1 and 9

Answer: y=4x-1
Step-by-step explanation: the line goes through (-2,7) and is perpendicular to the line x-4y =24
Answer: B(7,0)
Step-by-step explanation:
Since coordinate of A(3,8) and M(5,4), where M is the midpoint of AB.
Let the coordinate of B be (x,y)
Therefore, the distance AM is equal to distance MB.
Distance = sqrt{ (5 - 3)² + (4-8)² } =sqrt { (x-5)² + (y-4)²}
Comparing corresponding coordinates,
5-3 = x-5
x= 5+5-3 = 7
4-8 = y-4
y= 4-8+4= 0
Therefore, the coordinate of B is (7,0)
