Question

Can someone please give the equation for this problem. Please no fake answers.

Answer 1

y = 0.8x + 0.5

Explanation:

Let the equation of the line passing through a point (x', y') is,

y - y' = m(x - x')

Here, m = slope of the line

Slope of a line passing through two points
`(x_1,y_1)` and
`(x_2,y_2)` is,

m =
`(y_2-y_1)/(x_2-x_1)`

From the table attached,

Line represented by the table passes through two points (1, 1.3) and (1.5, 1.7).

Therefore, slope of the line (m) =
`(1.7-1.3)/(1.5-1)`

m =
`(0.4)/(0.5)`

m = 0.8

Equation of the line passing through (1, 1.3) will be,

y - 1.3 = 0.8(x - 1)

y = 0.8x - 0.8 + 1.3

y = 0.8x + 0.5
