Answer:
y= -x+2
Step-by-step explanation:
given that line m, passes through (2,-7) and (4,-9)
(refer to attached)
slope of line m,
= [(-7) - (-9)] / (2- 4)
= (-7 +9) / (2- 4)
= (2) / (-2)
= -1
recall that the general form of a linear equation is
y = mx + b, where m is the gradient.
in this case, we found that m = -1, so look for the answer where the x-term has -1 as a coefficient, i.e the x-term is "-x"
By observation, we see that the only answer that has "-x" as part of the equation is A
