Answer:
for this graph the answer is D
An ordered pair (x,y) is a solution to a system of equations if it makes all the equations true.
Let's check whether (–1, 5) makes the equations true.
Plugging –1 in the first equation for x and 5 in for y, we get
–1 + 5 = 4: TRUE
Plugging –1 in the second equation for x and 5 in for y, we get
–1 – 5 = –6: TRUE
Since it makes both the equations true, it's a solution to the system of equations. So the answer choice is D, the 4th one.
#1)
incorrect slope is
y2 - y1
-------------
x1 - x2
answer is B
Answer:
1st - c
2nd - d
Step-by-step explanation:
jere is your answer
3/4 inch represents 1/8 mile, that means:
1/8 mile represented by 3/4 inch
1 mile will be : (3/4) inch ÷ (1/8)
= 3/4 × 8/1 = 6
1mile will be represented by 6 inches
So on the map it is 6 inches per mile
