Question

Which is the equation of a line that has a slope of -2/3 and passes through point

Answer 1

We have to find b

• (-3,-1)
• m=-2/3

$\\ \sf\longmapsto y=mx+b$

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

$\\ \sf\longmapsto -1=-2(-1)+b$

$\\ \sf\longmapsto -1=2+b$

$\\ \sf\longmapsto b=-3$

Now put in equation

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