(2, 6);y= -3x + 5 I need help writing a equation in slope intercept from the line

1 answer:

7 0

Slope intercept form is y = mx + b where m is the slope and b is the y intercept.

6 = -3 (2) + b
6 = -6 + b
b = 0 (there is no b)

So your equation would be:
y = -3x

Question 3

Fiesta28 [93]

Answer: y = -6x + 2

m = y_2 - y_1
/ x_2 - x_1

-10 - 8
/ 2 - (-1)

= -18/3 = -6

m (slope) = -6

y = mx + b
y = -6x +b

Find b using (-1,8)
y = -6x +b
8 = -6(-1) + b
8 = 6 + b
-6 -6
2 = b

Final answer: y = -6x + 2

To check using one of the points: (-1,8) or (2,-10)
y = -6x + 2
-10 = -6(2) + 2
-10 = -12 + 2
-10 = -10
This is a true statement.

Describe how you would write 5.04 X 10^6 in standard form.

Margarita [4]

You move the decimal point 6 places to the right because the exponent is positive.

5.04 x 10^6 in standard form is 5040000.

Which of these is the algebraic expression for 5 times the sum of 2 and y

Vaselesa [24]

The answer is d because 2+y is the sum of 2 and y and then you multiply it by 5
