Question 1001732: 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 have tried attempting this question but I get stuck

You can put this solution on YOUR website!
You have two points
(50,324)
(70,415)
Generate the equation of the straight line.
Then solve for the value at 95.
Find the slope.
m=%28415-324%29%2F%2870-50%29=91%2F20
Then using the point-slope form,
y-324=%2891%2F20%29%28x-50%29
Then,
y-324=%2891%2F20%29%2895-50%29
I'll leave you to solve for y to get the final answer.
