A standard equation for a line is usually written as y=mx+b, m being the slope and b the y-intercept. We already have the slope, 7. To find the y-intercept we need to make an equation. The coordinates (1,2) will help us. We can plug the x from our point into the equation as well as our y. 1 is the x and 2 is the y. Therefore our equation is 2=7(1)+b. Now we solve. 7×1=7, so 2=7+b. Then we subtract 7 from both sides to get rid of the 7 on the right side. In addition, the 7 is positive so subtracting will get rid of it.
2=7+b
-7 -7
2-7 is -5. Therefore -5 is b.
Now we can make an equation.
y will remain y.
x will remain x.
m = 7
b = -5
y=7x+(-5) or y=7x-5
I hope this helped! (:
Answer:
Third option: Rocks being broken apart
Step-by-step explanation:
Have a good day :)
Using the Pythagorean theorem:
X = sqrt(26^2 - 10^2)
X = sqrt(676-100)
X = sqrt(576)
X = 24
Answer: 24
