Write the equation of a line that passes through the points (-3, 7) and (3, 3).
egoroff_w [7]

Answer:

y = -2/3x + 5

Step-by-step explanation:

(-3, 7) and (3, 3)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(3 - 7) / (3 -(-3))

Simplify the parentheses.

= (3 - 7) / (3 + 3)

Simplify the fraction.

= (-4) / (6)

= -4/6

= -2/3

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -2/3x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 3). Plug in the x and y values into the x and y of the standard equation.

3 = -2/3(3) + b

To find b, multiply the slope and the input of x(3)

3 = -2 + b

Now, add 2 to both sides to isolate b.

5 = b

Plug this into your standard equation.

y = -2/3x + 5

This is your equation.

Check this by plugging in the other point you have not checked yet (-3, 7).

y = -2/3x + 5

7= -2/3(-3) + 5

7 = 2 + 5

7 = 7

Your equation is correct.

Hope this helps!

Suppose y varies directly with x. When<br> X is 2, y is 10. What is y when x is 4?
melomori [17]
X:y

2/10 = 4/x

Cross multiply

2x X= 10x4

2x = 40

Eliminate

2x/2 = 40/2

x = 20

How do u add 10 to 2 digits numbers
SVETLANKA909090 [29]
It depends. Multiples of 10 are:
10, 20, 30, 40, 50...........
And a 2 digit number can be anything between 10 and 99.
