Answer:
y=-9/6x+1
Step-by-step explanation:
Slope=y2-y1/x2-x1
1) Find the slope of the line:
(-5-4)/(4+2)
2) Simplify:
m= -9/6
3) Now plug in the slope into point slope formula: (attached as picture)
(y-4)=-9/6(x+2)
4) Distribute -9/6 to x and 2:
y-4=-9/6x-3
5) Add 4 to both sides:
y=-9/6x+1
Answer:
The correct answer is "B", we first need to add 40 to both sides of the equation.
Step-by-step explanation:
Since we have the following quadratic equation:
The first step to solve it is to isolate the independent variable, "x". To do that we must add +40 on both sides of the equation, since that way the "-40" on the left will be gone in a way that maintains the validity of the equation as shown below:
After this step we take the square root of both sides:
Therefore the correct answer is "B".
