Answer:
The equation is y = -x + 4
Step-by-step explanation:
This is a very trivial exercise:
The general equation of a line is given by:
y - y₁ = m(x - x₁)
where m = slope of the linear graph
From the given graph, it can be observed that the coordinate (x₁, y₁) and (x₂, y₂) are (0, 4) and (4, 0)
The slope, m = (y₂ - y₁)/(x₂ - x₁)
m = (0 - 4)/(4 - 0)
m = -4/4
m = -1
Substituting the values of (x₁, y₁) = (0, 4) and m = -1 into the general equation:
y - y₁ = m(x - x₁)
y - 4 = -1 (x - 0)
y - 4 = -x
y = -x + 4
Answer:
y = -3
x = -2
Step-by-step explanation:
2x - y = 17
y = x - 10
Adding these 2 equations:-
2x + y - y = 17 + x - 10
2x = x + 7
x = 7
Now substitute for x in the first equation:-
2(7) - y = 17
14 - 17 = y
y = -3 (answer)
Last equation:-
x + 3y = 16
4x - 5y = -38
Now multiply first equation by 5 and the second by 3:-
5x + 15y = 80
12x - 15y = -114 Adding:-
17x = -34
x = -2 (answer)
