4x+2y=10 Equation 1
x-y=13 Equation 2
Solving by substitution method.
Isolate x from equation 2.
x=y+13
Substitute value of x in equation 1
4(y+13)+2y=10
4y+52+2y=10
6y+52=10
6y=-42
y=-7
Now substitute value of y in x=y+13
x=-7+13
x=6
Answer: (6,-7)
The answer is A I believe
Answer:
A
Step-by-step explanation:
the answer is A. if you notice the y-intercept, it its at -5
A is the only answer choice that gives -5 as the y-intercept
another way to make sure that A is the right answer is to calculate the slope
when you increase 3 units UP (y), you increase 5 units to the RIGHT (x)
since slope is y/x, it should be 3/5 which is also in A
another way to check A is to plug in points
hope this helps!
