So the coordinates are written (x,y) so if you have a graph you would oput the first dot at 1 over,2 up as x avis is the horizontal axis and y is vertical, then your next dot would be three over ,10 up and then your last dot would be 5 over and 18 up, your intercept is where your line meets your axis

AURORKA [14]

Answer:

number of message sent by Scott is 23

number of message sent by Christine is 30

number of message sent by Milan is 92

Step-by-step explanation:

Total message sent by Christine,Milan, and Scott : 145

Let number of message sent by Scott be x .

Given that Christine sent 7 more messages than Scott

number of message sent by Christine is x+7

It is also given that Milan sent 4 times as many messages as Scott

number of message sent by Milan is 4*x = 4x.

Thus, sum of message sent by Christine,milan, and Scott in terms of x

= x + x + 7 + 4x = 6x + 7

we already know that Total message sent by Christine,milan, and Scott is 145

thus, 6x + 7 should be equal to 145

6x + 7 = 145

=>6x = 145 - 7 = 138

=> x = 138/6 = 23

Thus,

number of message sent by Scott is x = 23

number of message sent by Christine is x+7 = 23+7 = 30

number of message sent by Milan is 4x = 4*23 = 92
