Answer:
h = 
Step-by-step explanation:
Given
ba - ha = c ← factor out a from each term on the left side
a(b - h) = c ← divide both sides by (b - h)
a = 
This is a linear function. you can list out a group of domains or x, then you will get outcomes, which will be your range
Answer:
m=6/7
Step-by-step explanation:
If you graph both of these points and use the rise over run method getting 6/7 as your slope or m.
1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation
x = - (-8)/2(-2) = 8/ -4 = -2
y = -(8^2-4(-2)(1)/ 4(-2) = -(64-8) /-8 = 56/8 = 7
v(-2,7)
