Question

Write the equation in standard form and slope-intercept form: Line Containg (4,-1) and having a slope of 5/2

Answer 1

ok, so slope-intercept form is the form:

y=mx+b

where m is your slope and b is your y-intercept. so plug in your slope that you know already:

y=(5/2)x + b

now solve for b by plugging in the point you already have since (x,y) = (4,-1) we plug in:

-1=(5/2)(4) + b

and solve to get:

-1=10+b
-11=b

so your equation is:

y=(5/2)x-11

Answer 2

Thanks for the help! Do you know how to write the equation in standard form?

Answer 3

no prob! standard form is just the same thing but written with both x and y on the same side of the = so it would be

y-(5/2)x=-11

Answer 4

Thank you!

Answer 5

no prob, good luck with the homework
