Answer:
A) y = 4/3 x - 1/3
Step-by-step explanation:
(4,5) and (-2,-3)
Slope = (5 + 3)/(4 + 2)
= 8/6
= 4/3
Equation
y + 3 = 4/3(x + 2)
y + 3 = 4/3 x + 8/3
y = 4/3 x + 8/3 - 9/3
y = 4/3 x - 1/3
Answer:
y = 4/3 x - 1/3
Solution set is: (
)
Option B is correct
Step-by-step explanation:
We need to find the solution to system of equations
Let:
Putting value of y from eq(2) into eq(1)
So, value of x=7
Putting value of x into equation 1 to find the value of y:
So, value of y = 
Solution set is: ()
Option B is correct

A) x + y = 17
B) x - y = 27
Adding both equations:2x = 44
x = 22
y = -5
425 is decreased to 319.
The above statement means that a number should be deducted from 425 to get the difference of 319.
Let x be the unknown number.
425 - x = 319
425 - 319 = x
106 = x
106 is the unknown number.
It can be phrased like this: 425 decreased by 106 is 319.
