Question

Please help me with my math please?

Answer 1

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

Step 1

y = mx + b,  Identify:  x = 2, y = -1, slope: $\sf \frac{1}{3}$

insert following values

$\rightarrow \sf -1 = \dfrac{1}{3} (2) + b$

multiply

$\rightarrow \sf -1 = \dfrac{2}{3} + b$

switch sides

$\rightarrow \sf b = -1 - \dfrac{2}{3}$

subtract

$\sf \rightarrow b = -\dfrac{5}{3}$

convert to mixed fraction

$\sf \rightarrow b = -1\dfrac{2}{3}$

Step 2

y = mx + b,  m = $\sf \frac{1}{3}$, b = $-1\frac{2}{3}$

insert following values

$\rightarrow \sf y = \dfrac{1}{3} x -1\dfrac{2}{3}$

Answer 2

Answer:

y = y coordinate

m = slope

x = x coordinate

b = y intercept
