Answer:
y=
+ 
you first find the gradient of the line by picking out any two coordinates then u fill the values in the equation of a line
50 - [(6² - 24) + 9√25]
= 50 - [36 - 24 + 9*5]
= 50 - [12 + 45]
= 50 - 57
= -7
A). Remember the equation y=mx+b. The b is the y intercept, and the m is the slope. Plus, if you look at the equation, a) is the only one with - 3/4 in it
That would be (20+30+56)/200 = 106/200 = 53/100 Answer
