Step-by-step explanation:
Remark
The slope intercept line is written as y = mx + b in it's general form.
You can get the slope, m, immediately because it is given as -2
So far what you have is y = -2x + b
y intercept
To get the y intercept, use the point (-3 , 4)
x = - 3
y = 4
4 = -2*(-3) + b
4 = 6 + b Subtract 6 from both sides
4 - 6 = 6-6 + b
b = - 2
Line
y = -2x - 2
(a,8)
y = -2a - 2
8 = -2a - 2 Add 2 to both sides
8 +2 = -2a -2+2 Combine
10 = - 2a Divide by - 2
10/-2 = a
a = -5
(5,b)
y = -2x - 2
x = 5
y = b
b = -2*5 - 2
b = -10 - 2
b = - 12

Step-by-step explanation:
Given --> 
Substitute into the equation and solve for 
:
So, when 
The point would be (-4,-9) im pretty sure
Answer:
Step-by-step explanation:
Here we need to find the x for the given equation so we can use the concept of the quadratic formula to solve .
comparing the given equation with an standard quadratic equation we get
a=1
b=6
c=3
so applying the quadratic formula we get
which can be further simplified to get
x=-5.45 or x=-0.55
so correct option is <em>A</em>
