With an equation like this. you will try to rewrite it in slope-intercept form:y=mx+b. Therefore you will start by trying to get y by itself.
Add x to both sides to get -2y=x-10.
Then proceed to divide both sides by -2 to get y=-1/2x+(-10/-5)
Two negatives dividing will result in a positive number.
Thus, your slope intercept will be y=-1/2x+5
Three points can be (0,5), (1,9/2), and (2,4).
Answer:
8
Step-by-step explanation:
Since she now has 12, subtract 8 because of the 8 she before added.
Now, you're left with 4.
The 4 is half of what she originally had, leading up to the fact that the answer is 8.
Sally began with eight comic books.
From the markings and lines, we can tell this is an equilateral triangle. Since it is an equilateral triangle, we know that each angle is 60°.
Using this information, we can make and solve an equation:
8y - 4 = 60° <em>(we know that it is equal to 60°, since it is an equilateral triangle)</em>8y = 64° <em>(we added both sides by 4 to get the y's alone on one side)</em>y = 8° <em>(we divide both sides by 8 to find out what just y is)</em>-------------------------------------------------------------------------------------------------------------Answer:
So y is equal to 8°
Slope is 3 so the equation is y-2=3(x-1) in point slope form as y-y1 =m (x-x1)
