Question 1001745: In a test of a certain lifting machine it is found that an effort of 50N will life a load of 324 N and that an effort of 70 N will lift a load of 415 N assuming that the graph of effort plotted against load is a straight line find the probable load that will be lifted by an effort of 95 N
I understand that when plotting my graph X = 95 N but what is my Y ?

You can put this solution on YOUR website!
you are being asked to find y when x = 95.
They told you the plot is linear and then gave you two points on the line. Use that information to find the slope of the line
slope+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29
slope+=+%28415+-+324%29%2F%2870+-+50%29
slope+=+91%2F20
Now you are asked to find the point on the line that is (95,y)
slope+=+%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29
91%2F20+=+%28y+-+415%29%2F%2895+-+70%29
91%2F20+=++%28y+-+415%29%2F%2825%29
%2891%2A25%29%2F20+=+y+-+415
113.75+=+y+-+415
528.75+=+y
