Write an equation in slope-intercept for the line described. Slope 3, passes through (0,-2)

Question

anonymous · Answer

okay well what form is the equation going to take? what is the general form?

anonymous · Answer

captainmico88 I am not going to give you the answer but I will work through it with you if you respond

anonymous · Answer

What is general form i don't understand

anonymous · Answer

the general equation for slope intercept form is
$$y=mx+b$$

anonymous · Answer

where m is the slope and b is the y intercept

anonymous · Answer

So?m is 3? And x is 0 i dnt get it explaain further

anonymous · Answer

well you got the first part correct....how about we do a little algebra to help you with the "+b" part okay?

anonymous · Answer

so you got the equation this far
$$y=3x+b$$
now we can plug in the coordinates they gave us and solve for b

anonymous · Answer

can you try plugging in those coordinates for me?

anonymous · Answer

Sure explain

anonymous · Answer

(0, -2)

anonymous · Answer

plug in the x coordinate into our formula with the slope for the x variable do the same with the y coordinate for the y variable in that same equation

anonymous · Answer

Y=3x+-2

anonymous · Answer

well it would be better to just write y=3x-2 but you are correct

anonymous · Answer

Okay then?

anonymous · Answer

Is that it? Thats the answer?

anonymous · Answer

yup that is a equation in slope intercept form with a slope of 3 that passes through the point (0,-2)

anonymous · Answer

How bout this pne? Slope -2, passes through (-3,14)

anonymous · Answer

post that as a separate question and close this one
