Your percentage of change would have to be about 21.05, but the full answer is 21.05263. Since we are going to need to round to the nearest percent, you would have 22% decrease. The difference in the change is -20.
intersecting circles have two common tangents
Answer: y = -
x - 6
Step-by-step explanation:
The line crosses the y intercept at y = -6
The slope of the graph looks negative, as it extends from the top left quadrant to the bottom right quadrant.
A key trick is to use rise/run to figure out the slope:
Between each dot on the line, it rises 2 and runs -3 (negative because the direction is left).
So your equation would be: y = -
x - 6
Point Slope:
y-12=-3(x-6)
From there you can find the slope intercept form:
y-12=-3x+18
y=-3x+30
