The formula to find slope is (y2-y2)/(x2-x1)
You can remember it like this: "If you want to be wise, remember rise over run, which is y's over x's."
The next step is to determine which point is (x1,y1) and which is (x2,y2).
We do this by determining which point has the biggest x value: (8,7)
Now we plug it into the formula: (8-4)/(7-1)
Simplify and we get: 4/6 or 2/3
Voila! You have your slope: 2/3
Hope this helps, and May the Force Be With You.

Answer:
Step-by-step explanation:
Let's call B at the base of the triangle and call h at the height of the triangle. Then we know that:
The height of a triangle is 5 cm shorter than its base. This means that:
.
The area of the triangle is 25 cm²
By definition the area of a triangle is:
For this triangle we know that and . We substitute these values in the equation and solve for B.
Now we use the quadratic formula to solve the equation.
For an equation of the form the quadratic formula is:
In this case note that:
Then:
The solutions are:
For this problem we take the positive solution.
Now we substitute the value of B in the equation to find the height h
