1. The Formula Straight Line Equation through betoken A(x1, y1) as well as B(x2, y2)
The formula right away ine equation through betoken A(x1, y1) as well as B(x2, y2) is :
Example :
Find the equation of the trouble through the points (3, -4) as well as (-2, 6)!
Answer :
x1 = 3
y1 = -4
x2 = -2
y2 = 6
-5(y + 4) = ten (x - 3)
-5y - xx = 10x - 30
(-5y - 20)/5 = (10x - 30)/5
-y - iv = 2x - 6
-y - iv + iv = 2x - vi + 4
-y = 2x - ii or y = -2x + 2
So the equation of the trouble through the points (3, -4) as well as (-2, 6) is -y = 2x - ii or y = -2x + 2.
2. The Formula Straight Line Equation that has a slope 1000 as well as through betoken Influenza A virus subtype H5N1 (x1, y1)
The formula right away trouble equation that has a slope 1000 as well as through point A(x1, y1) is:
Example :
Find the straight-line equation 2 as well as through the betoken (-3, 1)!
Answer :
So the straight-line equation which is graded 2 as well as through the betoken (-3, 1) is y = 2x + 7.
