Answer:
y=5x+29
Step-by-step explanation:
1. find slope
y2-y1/x2-x1
9--6/-4--7= 15/3=5
2. substitute x and y
(-4, 9)= 9=5(-4)+b
9=-20+b
29=b
3. put it together
y=5x+29
Answer:
The sum of two numbers is 18.
5 times the first number subtracted from 4/7 of the second number is 14.
First number --> x
Second number --> y
so
x + y = 18 --> x = 18-y
5x - (4/7)y = 14
so
5 (18-y) - (4/7)y = 14
90 - 5y - 4/7 y = 14
-5.57 y = 14-90
y = 13.64
so
x = 18 - 13.64
x = 4.36
