An equation of the circle with center (h, k) and radius r:

Answer:
B -3.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1)
= (-2-4)/(8-6)
= -6/2
= -3.
Slope-intercept form is y=ax+b where a is the slope and b is the y-intercept.
Start by getting y alone on one side.
5x-7y=-45
5x+45=7y
Then divide both sides by 7 to get y alone.
y= 5/7x + 45/7
