Answer:
y = 2.9x + 5.8
Explanation:
get any two pairs of coordinates and find the slope
(2, 11.6) and (4, 17.4)
use the formula to find the slope, changes in y over changes is x
(17.4 - 11.6)/(4 - 2)
5.8/2 = 2.9
slope is 2.9
use y = mx + b and plug in any one pair of coordinate to find b or y-intercept. I will use (2, 11.6)
11.6 = 2.9(2) + b
11.6 = 5.8 + b
11.6 - 5. 8 =b
5.8 = b
therefore the equation is
y = 2.9x + 5.8
