First, put it into point-slope form.
Find the slope:
m=(y2-y1)/(x2-x1)
m=(-6-(-2)/(2-1)
m=(-6+2)/1
m=-4/1
m=-4
Now, put it into point-slope:
y-y1=m(x-x1)
y-2=-4(x-(-6)
y-2=-4(x+6)
y-2=-4x-24
Slope intercept form: y= mx+b
Add 2 to the other side.
y=-4x-22 <== the answer
I hope this helps!

Answer:
9
Step-by-step explanation:
The first sentence of the problem can be interpreted two ways. The way that makes the second sentence work out correctly is ...
'a larger number is 5 less than 3 times a smaller number'
Using x for the smaller number, the two equations that can be written are ...
Adding 4 times the first equation to the second, we get ...
4(3x -y) + (x +4y) = 4(5) +(97)
13x = 117 . . . . . simplify
x = 9 . . . . . . . . divide by 13
The smaller number is 9.
Given,
Diameter of circle=15cm
so, radius= D/2= 15/2
we know that circumference=perimeter
2πr= 2×22/7×15/2=47.1428cm
The solution to this equation is (-3,3)
The answer is 2! because the Y axis is going up by 2 every time. the X axis is going up by 0.4. 0 is where the y axis starts and 1 is where the x axis starts. 2 is the answer!!
