Answer:
3
Step-by-step explanation:
First you gotta take the equation and bring it to the following form:

The slope of the line is the coefficient of x, a.
In other words:

So, as we can see, the number infront of x is 3. That is to say that the slope of this line is equal to 3.
Answer:
it would be about 63.44..
Step-by-step explanation:
you can do 230/87=24/x where x is the new height, when you cross multiply and divide, x should be about 63
4x + 2y = 24
2y = -4x + 24
y = (-4/2)x + 24/2
y = -2x + 12 <===
Answer:
Slope is 5/2
Step-by-step explanation:
5x-2y=10
subtract 5x from both sides
-2y=-5x+10
Then you divide -2 on both sides
y=5/2x-5
Which will result 5/2 as the slope
