Answer:
y = -7x + 2
Explanation:
For such questions, mark any two points and find their coordinates.
In this case we consider (0,2) and (1,-5).
now we got our two points, the general equation of a line is given as :
y = mx+c;
here m is the slope which is given as :

m = (-5-2)/(1-0) = -7
y = -7x +c ;
now we need to find c , so we subsitute the point (0,2) in it
2 = 0 +c , hence c is 2
this results in the equation of line as y = -7x +2 .
