Question

Please help me with my math please?

Answer 1

y = y coordinate

m = slope

x = x coordinate

b = y intercept

Answer 2

Line passes through (2, -1) and slope of 1/3

Step 1

y = mx + b, Identify: x = 2, y = -1, slope:
`\sf (1)/(3)`

insert following values

`\rightarrow \sf -1 = (1)/(3) (2) + b`

multiply

`\rightarrow \sf -1 = (2)/(3) + b`

switch sides

`\rightarrow \sf b = -1 - (2)/(3)`

subtract

`\sf \rightarrow b = -(5)/(3)`

convert to mixed fraction

`\sf \rightarrow b = -1(2)/(3)`

Step 2

y = mx + b, m =
`\sf (1)/(3)`, b =
`-1(2)/(3)`

insert following values

`\rightarrow \sf y = (1)/(3) x -1(2)/(3)`
