Question

PLEASE HELP!!!!! 61 POINTS AND IM TIMED

Mac drew the line of best fit on the scatter plot shown below:

A graph is shown with scale along x axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 15 at increments of 1 and scale along y axis from 0 to 15 at increments of 1. The ordered pairs 0, 3 and 1, 4 and 2, 4 and 3, 6 and 4, 7 and 5, 8 and 6, 10 and 7, 12 and 8, 13 and 9, 14 and 10, 15 are shown on the graph. A straight line joins the ordered pairs 0, 2 and 10, 15.

What is the equation of this line of best fit in slope-intercept form?

y = 2x + 13 over 10
y = 10 over 13x + 2
y = 13 over 10x + 2
y = 2x + 10 over 13

Answer 1

y = 13/10x + 2 <==

Explanation:

(0,2),(10,15)

slope = (15 - 2) / (10 - 0) = 13/10

y = mx + b

slope(m) = 13/10

(0,2)...x = 0 and y = 2

sub and find b

2 = 13/10(0) + b

2 = b

Answer 2

Explanation:

(0,2),(10,15)

slope = (15 - 2) / (10 - 0) = 13/10

y = mx + b

slope(m) = 13/10

(0,2)...x = 0 and y = 2

sub and find b

2 = 13/10(0) + b

2 = b

ur equation is : y = 13/10x + 2 <==
