Question

Equation of line parallel to x+y=7 and passing through the point (1,2) is

Answer 1

Step-by-step explanation:

Given that:Equation of line parallel to x+y=7 and passing through the point (1,2).

Solution: To find the equation of line,one have two requirements

One is the coordinates of passing and other slope.

If two lines are parallel then their slopes are equal.

Write the given equation in the form of

y= mx+c

y=-x+7

Slope is m= -1

Now equation of a line passing through a point of given slope m

$\boxed{\bold{y-y_1=m(x-x_1)}}$

Put the value of m and point(1,2)

$y-2=-1(x-1)\\\\y-2=-x+1\\\\y+x=1+2\\\\x+y=3$

Thus,equation if that line is x+y=3.

Hope it helps you.

Answer 2

Answer:

equation if that line is x+y=3.
