Use a graphing calculator to find an equation of the line of best fit for the data. round the slope to the nearest tenth and the y-intercept to the nearest integer. X : -4 , -2,0,2,4,6,8,10
Y: 17,7,8,1,5,-2,2,-8

Identify the coefficient. Round to the nearest tenth

Help ! I don’t know how to solve this I keep on getting the wrong answer :( thanks !

answer: i cant see the picture

step-by-step explanation:

can u take a better picture

what do you need me to answer?

step-by-step explanation:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
