The equation of the line of best fit of a scatter plot is y = -8x + 3. 
This equation is in slope-intercept form, or y = mx + b, where m is the slope and b is the y intercept.

Thus, the y intercept in this equation is 3.

AysviL [449]
(6 • 2 - 2x + 16) + (4 • 2 + 7x - 55)
(-2x + 16 + 6 • 2) + (7x - 55 + 4 • 2)
(-2x + 16 + 12) + (7x - 55 + 8)
-2x + 28 + 7x - 47
-2x + 7x + 28 - 47
5x + (-19)
5x - 19
So the answer is 5x - 19.

Nataly [62]
2(-8x-2y=-22)
16x+7y=17

-16x-4y=-44
16x+7y=17

3y=-27
y=-9

16x+7(-9)=17
16x+-63=17
16x=80

I have to find the angle measurements of a interior triangle a is 4x b is 7x-2 and c is 5x-10
RSB [31]

Answer:

m\angle a=48^o\\m\angle b=82^o\\m\angle c=50^o

Step-by-step explanation:

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

m\angle a+m\angle b+m\angle c=180^o

substitute the given values

4x^o+(7x-2)^o+(5x-10)^o=180^o

solve for x

(16x-12)^o=180^o

16x=180+12\\16x=192\\x=12

Find the angle measurements

m\angle a=4(12)=48^o

m\angle b=7(12)-2=82^o

m\angle c=5(12)-10)=50^o
