Question

What is the equation of the line passing through (1, 7) and parallel to the line y = –x + 5 in standard form?

Answer 1

y=-x+8

Answer 2

parallel lines have the same slope

Answer 3

these are the options:

x + y = 8

x – y = 8

x + y = –8

x – y = –8

Answer 4

a

Answer 5

being parallel to y=-x+5 your required equation is y=-x+k(say) as parallel lines have the same slope
since the line passes through (1,7) substitute in the above equation 7=-1+k
which gives you k=8
therfore the requied equation is y=-x+8

Answer 6

so its a

Answer 7

Solve the following for x and them move -y from the RHS to the LHS.\[\frac{y-7}{x-1}=-1\]
\[x+y=8 \]
