Answer:
if that line follows y=mx...then answer is A
But it seems not....when we divided valuse like 60/2=30
75/3=25....
ratio is not the same
Its hard to tell....You must know exact cordinations
I can tell you this
I can say this if y=60 and x=2 and....y=120 and x=4...then it is propotional...but it seems not..
Answer:
(-2, 3)
Step-by-step explanation:
Given the system of equations:
-3x + 2y = 12
x = 2y - 8
You can 'substitute' the expression '2y - 8' for the value of 'x' in the first equation and solve for 'y':
-3(2y - 8) + 2y = 12
Distribute: -6y + 24 + 2y = 12
Combine like terms: -4y + 24 = 12
Subtract 24 from both sides: -4y + 24 - 24 = 12 - 24 or -4y = -12
Divide both sides by -4: -4y/-4 = -12/-4 or y = 3
Use y = 3 to solve for 'x':
x = 2(3) - 8 or 6 - 8
x = -2
(-2, 3)
2x = 360/4
x = 90 / 2
x = 45
Hope this is the answer you are looking for!
You put the equation in slope-intercept form by solving for y.
.. 7y = -6x -42 . . . . . .subtract 6x
.. y = (-6/7)x -6 . . . . . divide by 7
Compare this to the pattern
.. y = mx +b
The slope is the coefficient of x, m = -6/7.
The intercept is the constant term, b = -6.
