Which equation is in point-slope form and depicts the equation of this line? (the slopes are (2,1)(-1,-4)

Question

sleepyhead314 · Answer

first find the slope between the points, can you do that? :)

anonymous · Answer

no :(

sleepyhead314 · Answer

$$slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} } $$when given points (x1, y1) and (x2, y2)

anonymous · Answer

$$y = \frac{ 5x }{ 3 } - \frac{ 7 }{ 3 }$$There is your solution to your question.

My pleasure! If you ever need my assistance you can tag me in your question by typing @Rachella and I'll be more than happy to help you.

anonymous · Answer

That is in point-slope form.

sleepyhead314 · Answer

point slope form: y - y1 = m(x - x1)
when m = slope and given the point (x1, y1)

slope-intercept form: y = mx + b
when m = slope and b = y-intercept

anonymous · Answer

(2,1) and (-1,-4) 

Point-Slope Form: y – y1 = m(x – x1)

(2,1) and (-1,-4) in Point-Slope Form would be: $$y = \frac{ 5x }{ 3 } - \frac{ 7 }{ 3 }$$Hold on, I can give a calculator to prove myself.
