Answer:

Step-by-step explanation:

So from the first graphs equation is

2x-y=-1

therefore if we made y the subject of the formula, the equation would be

2x+1=y , this is also the same as y=2x+1

from this, the equation is clearly in the form y=mx+c so we can get the gradient

The gradient of graph one would be 2

The perpendicular gradient would be the negative reciprocal of graph one's gradient which would be -1/2

Now we look at our options and see which one has the gradient as -1/2

Find the point-slope equation for

iris [78.8K]

Answer: y+9=-2(x-9)

Step-by-step explanation:

The point-slope equation is $y-y_{1} =m(x-x_{1} )$ . All we have to do is fill in all the values except for y and x.

To find m, you use $\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$ . Since we are given 2 points, we cna plug them in.

$\frac{13-(-9)}{-2-9} =\frac{22}{-11} =-2$ . Now that we have our slope m, we can fill in the point slope equation.

$y-(-9)=-2(x-9)$

$y+9=-2(x-9)$
