(1,4) (3,8) and (6,y). what is the value of y?

The formula for point slope form is:

y − y1 = m(x − x1)
 where (x1,y1) is a point on the graph and m=slope

now lets solve for the slope of our points: (1,4) (3,8)

Slope=y2-y1/x2-x1=8-4/3-1=4/2=2

Now we can plug our information into the equation

y − y1 = m(x − x1)
y-4=2(x-1)

Now lets convert it to slope intercept form

y-4=2(x-1)
add 4 to both sides
y=2(x-1)+4
y=2x-2+4
y=2x+2

Now we can solve for the missing y value in (6,y) by plugging in the x value.

y=2x+2
y=2(6)+2
y=12+2
y=14

So the ordered pair would be (6,14)

Answer=14

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
