Answer:
2x - 5y = -13
Step-by-step explanation:
The equation of a straight line can be written as
(y - y1) = m(x - x1), where the coordinates are (x1,y1) and gradient is m.
Hence by applying this formula, we get:
y - 1 = 2/5 (x + 4)
5y - 5 = 2(x + 4) (Multiply both sides by 5)
5y - 5 = 2x + 8 (Expand the Right Hand Side)
5y - 2x = 13 (Bring the variables to one side)
2x - 5y = -13 (Multiply both sides by -1)
Hence Answer is <u>2x - 5y = -13</u>
25) It is a right triangle
3²+4²=5²
9+16=25
25=25
26) It is a right triangle
6²+8²=10²
36+64=100
100=100
27) Not a right triangle
5²+5²=10²
25+25=100
50=100
28) It is a right triangle
5²+12²=13²
25+144=169
169=169
Hope this helps :)
