Question

Write an equation of the line in slope-intercept form. Coordnates -1,3 and 0,4

Answer 1

y = x + 4

Explanation:

`slope \: (m) = (3 - 4)/( - 1 - 0) = ( - 1)/( - 1) = 1 \\ y - intercept \: (b) = 4.. \{from \: (0, \: \: 4) \} \\ equation \: of \: line \: in \: slope \: intercept \: \\ form \: is \: given \: as: \\ y = mx + b \\ \therefore \: y = 1 * x + 4 \\ \huge \purple{ \boxed{\therefore \: y = x + 4}} \\ is \: the \: required \: equation.`
