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:
X = 3
Y = all real numbers
Step-by-step explanation:
x is the input
y is the output
The equation would be x = 3
200+200+200+200+200+200+200+200+200
Answer:
x = ± 2
Step-by-step explanation:
Given
x² = 20 ( take the square root of both sides )
x = ±
= ±
= ± 2
