Question

Write in y= mx + b form: a line through (-3,1) having the same y-intercept as the graph of x-2y=-4

Answer 1

Explanation:

Aight, so the same intercept

`- 2y = - 4 - x = = = > \\ y = (1)/(2) x + 2`

m=½

`y = (1)/(2) x + b = = = > \\ now \: let \: us \: replace \: the \: point \\ 1 = (1)/(2) ( - 3) + b = = = > \\ (5)/(2) = b`

soooo

`y = (1)/(2) x + (5)/(2)`
