Answer:
Step-by-step explanation:
area=4×22/7×14²=4×22×28=2464 units²
63-x=62
Then subtract 62 and 63
-x=-1
x=1
Y2-y1/x2-x1 to find the gradient. So -1-8/4–8= -9/12. Then substitute into any of the coordinates. I chose -1=4(-9/12)+c. Rearrange to get c alone. Answer altogether is : y=-9/12x+2
No. For two lines to be perpendicular their slope must be the negative reciprocals of one another, mathematically:
m1*m2=-1
So if the slope of one line is negative, the line perpendicular to this must be positive by definition.
