Answer:
The value of y is -2
Therefore the given point (8,y) becomes (8,-2)
Step-by-step explanation:
Step-by-step explanation:
Given that the line through the points (8, y) and (9, 1) and slope m is 3
To find y to the line through the points (8, y) and (9, 1) :
The formula for slope is
Let , be the given points (8, y) and (9, 1) respectively
Now substitute the values of the points and m=3 in the formula
( adding the like terms )
Therefore y=-2
Therefore the value of y is -2
Therefore the given point (8,y) becomes (8,-2)
