Answer:
Step-by-step explanation:
We know that , the equation of a line that passes through (a,b) and (c,d) is given by :_

Standard form of equation of line = 
Given points = (7, -3) and (4, -8)
Then, the equation of a line that passes through the points . (7, -3) and (4, -8) is given by -

[∵ (-)(-)=(+)]
Or
Hence, the required equation :-
Answer:
2.8, 4.5, 5.3
numbers represent the measure of the sides of a right triangle.
2.8²+4.5²=5.3²
7.84+20.25=28.09
28.09=28.09
5(a - 2b) - 3(a - 2b) |use distributive property: a(b - c) = ab - ac
= 5a - 10b - 3a + 6b
= (5a - 3a) + (-10b + 6b)
= 2a - 4b
8.9. round the first 8 after decimal to 9 because the 8 after is 5 or above.
