Write an equation of a line that passes through (3,-2) and (-1,6).
1 answer:
Answer:
-2x -y = -4
Step-by-step explanation:
the formula for calculating the equation of the line passing through two points is (look at the photo)
3 is x1, -2 is y1, -1 is x2 and 6 is y2
solve: x-3/-1-3 = y-(-2)/6-(-2)
x-3/-4 = y+2/8
transport the second fraction to the left of the equal, then it becomes negative:
x-3/-4 - y+2/8 = 0
do the mcm: -2(x-3)-(y+2) = 0
solve (minus in front of a parenthesis changes all signs inside it): -2x+6-y-2 = 0
-2x+4-y = 0
move the unknowns to the left of the equal:
-2x -y = -4
