Answer:
-2.6
Step-by-step explanation:
11. y = -23x - 21
You can get this by starting with y = mx + b (slope intercept form). Then put in all the knowns and solve for the b.
2 = -23(-1) + b
2 = 23 + b
-21 = b
Then add that to the end of the equation with m = -23
12. -5
The y-intercept of an equation is always the number added on at the end of an equation. It is also the number with no x attached to it.
13. 8x^9y^6
When you use the law of exponents, you need to make sure the exponent goes to each individual term. When we cube the 2, it becomes 8. When you cube x^3, you get x^3*x^3*x^3 or x^9. And with y^2 you get y^6
Answer:
10, 14
Step-by-step explanation:
take the x values and plug into mid point formula and then divide by 2
so... (-214 + 234) divided by 2 = 10
do the same for the y values
so ... (14 + 14) divided by 2 = 14
so ... 10,14
(4,6), Using the midpoint formula which is (( x1 + x2)/2), ((y1+y2)/2)
