Answer: 
Step-by-step explanation:
To find the slope of the line , we will write the equation in the form:
where:
slope
y - intercept.
To write 
in this form , we will make y the subject of the formula.
Subtract 4x from both sides
Divide through by 2
Therefore :
25 times a letter Y = a number 5
The ones that match are
1 and 5
2 and 6
7 and 3
8 and 4
Answer:
The answer is -1 / 6
Step-by-step explanation:
use the formula y2 - y1 / x2 - x1 = m
7 - 8 / 10 - 4 = -1 / 6
