Answer:
y = -3/2 x +13
Step-by-step explanation:
We want our line to be perpendicular to
y = 2/3 x -1
The slope of this line is 2/3 (since it is written in the form y = mx+b and m is the slope)
Perpendicular lines have negative reciprocal slopes
m = -(3/2)
The slope of our new line is -3/2
We can use point slope form of the equation
y-y1 - m (x-x1)
y - 7 = -3/2 (x-4)
Distribute
y-7 = -3/2x +6
Add 7 to each side
y-7+7 = -3/2 x +6+7
y = -3/2 x +13
I don't really understand either but here is what I think:
1=m, 2=n, ect.
So what x and y could be:
X=12
Y=13
Im not sure but those are my answers. Hope it somehow helps!!

Answer:
A
Step-by-step explanation:
They are basically wanting the value of x.
These are 2 secant lines drawn. Secant Line is a line that intersects the circle at 2 points.
To solve this, we have to use secant-secant theorem.
Secant-Secant Power Theorem tells us that if 2 secant lines are drawn from external point (here, E) to a circle, then, product of measure of one secant's external part and total secant is equal to other secants external part and whole secant.
In algebra, that is:
Let's multiply and find the value of x:
Hence, the correct answer choice is A
(2,-4)(6,10)
slope(m) = (10 - (-4) / (6 - 2) = (10 + 4) / 4 = 14/4 reduces to 7/2
y = mx + b
slope(m) = 7/2
(2,-4)...x = 2 and y = -4
now we sub and find b, the y int
-4 = 7/2(2) + b
-4 = 7 + b
-4 - 7 = b
-11 = b
so ur equation is : y = 7/2x - 11
