Find two solutions of the linear equation 5x - 4y = -8
Answers
Answer:
1) 5x - 4y = - 8
let x = 0
so, 5(0)-4y=-8
0-4y=-8
y=-8/4
y=-2
2) 5x-4y=-8
let y = 1
5x-4(1)=-8
5x-4=-8
5x = -8/4
5x = -2
x = -2/5
Step-by-step explanation:
Answer:
Two solutions of the linear equation 5x - 4y = -8 are ( x=0,y=2 ) ,
( x= -8/5,y=0 ) .
Step-by-step explanation:
5x - 4y = -8
Using slope-intercept form, which is represented as : y = mx + b ,where
m is the slope of the line, b is the y-intercept, x and y are the coordinates of the x-axis and y-axis.
we can rewrite the given equation as : -4y = -5x -8 0r y=5/4 x + 2;..........(i)
- If the straight line is parallel to the x-axis, then the x-coordinate will be 0. Therefore, putting x=0 in the equation (i) we will get y=2.
Hence( x=0,y=2 ) is one solution for the given equation.
- If the line is parallel to the y-axis, the y-coordinate will be 0.
Therefore, putting y=0 in the equation (i) we will get
5/4x + 2 = 0
or, x=(-2)×4/5 =-8/5
Hence( x= -8/5,y=0 ) is another solution for the given equation.
