the important thing you need to know in solving mathematics is to understand the question and the formulae that follws.for finding equations ur general formulae us:
y-y1=m(x-x1)
do not solve y and x.
the y1 and x1 are ur x and y values from ur coordinates respectively.
m is ur gradient or slope given.
plug in the values.
Explanation:
y-y1=m(x-x1)
y-4=2/5(x-(-2))
the x-(-2) will change to positive thus giving you an equation of:
y-4=2/5(x+2).
option 1
hope i helped ❤
