Equation of a trendline is: y = 50x + 2. What is the value of y if x is given as 3.5?
A. 175
C. 180
B. 177
D. 201

B : 177

Step-by-step explanation:

hello :

put x=3.5 in the equation you have : y = 50(3.5)+2 =175+2=177

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
