I'm not understanding this at all, Write the equation of the line which passes through (–4, 2) and is parallel to y = –x + 6 in slope-intercept form
Write the equation of the line which passes through (–4, 2) and is parallel to y = –x + 6 in slope-intercept form
Tutors, please sign in to answer this question.
They gave you a line (y = -x + 6) which has a slope of -1 (the number in front of the x when the equation is in the form of y = mx + b; in other words, the "m").
Another line (the one you are about to find the equation for) is parallel to the above line. That means the line has the SAME slope, -1.
Now, use the formula y - y1 = m(x - x1) to solve for your answer (x1 and y1 come from the point (-4, 2) ):
So, y - 2 = -1(x - -4)
Remember that - -4 is really +4. After you distribute the -1 you get:
y - 2 = -x - 4
add 2 to both sides to get the final answer
y = -x - 2

Always write equation of line :
Y = mX + b , and then find values of m, b.
It is parallel with line Y = - X + 6
there for m = -1
Y = -X + b '
Passes through ( - 4 , 2) , therefore ( -4, 2 ) must be a point on line, and the coordinates should be plugged in the equation:
2 = - 4 + b , then b =6
The answer is Y= -X + 6
