Answer #1

y=3.51x-7.23.

y = - 7.23 + 3.51x

This is compared with the equation

where = - 7.23   and =3.51

and are y-intercept and slope respectively

Slope measures the sensitivity of y with respect to x. How much y would change due to a unit change o=in 'x'. A negative slope with have inverse relationship between x and y.

y-intercept shows the starting point of 'y' when x = 0
