Does the line have a slope sir/ma?

anonymous · Answer

im not sure does it? i have no clue where to start

isaiah.feynman · Answer

To find the equation you must have the slope and a point.

anonymous · Answer

so would the point be 2,8

wolf1728 · Answer

Slope = 8 - 0 / 2 - 0
Slope = 4

isaiah.feynman · Answer

If you don't have the slope then we can choose another arbitrary point just like @wolf1728 did. With that we can get the slope of the line which @wolf1728 just helped us with.

anonymous · Answer

ok

isaiah.feynman · Answer

Now that we have a slope and a point we can get the equation!!! Using the formula$$y-y1=m(x-x1)$$ where m is the slope,  y1=8, x1=2. Substituting, we get y-8=4(x-2). That simplifies to y=4x, and that's your equation!!!

anonymous · Answer

thank you i get the system of how it works now so you find the slope than enter it into the formula

isaiah.feynman · Answer

Exactly

isaiah.feynman · Answer

Remember if you don't have the slope you can choose another point ON the line that will enable you find the slope!
