Answer:
y=0.012x+0.65
Step-by-step explanation:
And again y=mx+c
we have 4 point given in the question
(50,1.25) ( 100,1.85) ( 150,2.45) (200,3.05)
we can find the M ( gradient/Slope) by using 2 of them with the formula
I am using the first 2 (50,1.25) ( 100,1.85)
which in decimal form is 0.012
with that cross out the first option as its wrong
now to find c, like in the previous two question, put the m, x and y in the equation and solve for C
I am gonna use the 3rd coordinates for this one (150,2.45)
2.45=0.012(150)+c
2.45=1.8+c
0=1.8-2.45+c
-c=-0.65
c=0.65
So our completed equation is y=0.012x+0.65
The third answer is correct :)
