Midpoint formula: (x1+x2/2 , y1+y2/2)
So, (-1+3/2 , 9+8/2)
-2/2 = -1 17/2 = 8.5
Answer: (-1,8.5)
Answer:
y=-2
Step-by-step explanation:
y+3y+5y=−18
Combine like terms
9y = -18
Divide each side by 9
9y/9 = -18/9
y = -2
The formula would be:
<span>y = mx + b
</span><span>
Now, let's look at the information we know.
m = slope
b = y-intercept
y-intercept = -6
x-intercept = -2
</span>
First, we would need to determine the slope. The formula for slope is m =

Plug your coordinates in and solve it.

= 6/-2 = -3
Now, since we have the slope and y-intercept, we are ready to plug them into the formula.
y = -3x - 6I hope this helps!
