For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1
So we first need to find the slope of the reference line.
m=(y2-y1)/(x2-x1)=(7-2)/(-1--5)=5/4
So the perpendicular line will have a slope of:
5m/4=-1
m=-4/5
So our perpendicular line so far is:
y=-4x/5+b, now we can use point (3,-1) to solve for the y-intercept, "b"
-1=-4(3)/5+b
-1=-12/5+b
-5/5+12/5=b
7/5=b
So the line is:
y=-4x/5+7/5 or more neatly
y=(-4x+7)/5
y=-0.8x+1.4
Answer:
series of directions for a training script
Step-by-step explanation:
Kevin is writing a series of directions for a training script. These directions will teach employees that have just been hired the step by step process on how to create the burgers at Outrageous Burgers. This way the new employees know exactly how the fast-food chain makes their burgers and they will be prepared to perform their responsibilities when customers start to come in and they are left by themselves. The training script is basically a resource for new hires.
