Answer:
x=a/(y-k)+h
Step-by-step explanation:
y-k=a/(x-h)
(y-k)(x-h)=a
xy-hy-kx+kh=a
xy-kx=a+hy-hk
x(y-k)=a+h(y-k)
x=a/(y-k)+h
I think it's B i jope that helps but here is some extra info if you like reading(lol)
Earlier in this chapter we have expressed linear equations using the standard form Ax + By = C. Now we're going to show another way of expressing linear equations by using the slope-intercept form y = mx + b.
In the slope-intercept form you use the slope of the line and the y-intercept to express the linear function.
<span><span>y=mx+b</span><span>y=mx+b</span></span>
Where m is the slope and b is the y-intercept.
Example
Graph the equation
<span><span>y−2x=1</span><span>y−2x=1</span></span>
rewrite in slope-intercept form
<span><span>y=2x+1</span><span>y=2x+1</span></span>
Identify the slope and the y-intercept
m = 2 and b = 1
Plot the point corresponding to the y-intercept, (0,1)
The m-value, the slope, tells us that for each step to the right on the x-axis we move 2 steps upwards on the y-axis (since m = 2)
