Answer:
(2,7) is not a solution to the given system of equations.
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
Answer:
the y intercept is -50
Step-by-step explanation:
in y=mx+b, m is the slope and b is the y intercept. We are given the point (900,1150) and a slope of 4/3
we can susbstitute 4/3 into the equation.
y=4/3x+b
since the line will go through the point (900,1150), we can plug it into the equation.
1150=4/3(900)+b
1150=1200+b
-50=b
we are left with the y intercept (b) being -50. As a point, it's (0,-50)
Hope this helps!
