hope this helps!!
We are given two points on a line. First we need to find the slope of the line using these two points.
The given points are (6, 1) and (5, 4). The slope (m) of the line will be:

Using the slope and the point (6,1) we can write the equation in point slope form as:
y - 1 = -3(x -6)
y = -3x + 18 + 1
y = -3x + 19
In standard form, the equation will be:
3x + y = 19
Answer: 21
Step-by-step explanation: All he did was took the amount of red and gave it a ratio of 7:1 meaning that he will increase the amount of red and make it 21 because the number 8 increased by 3 so 7 must increase by 3 as well.
6x+2+6x<14
add 6x+6x
12x+2<14
subtract 2 from both sides
12x<12
divide by 12
x<1
