Any idea?

anonymous · Answer

A line with points $(0,0)$ and $(1,7)$.

anonymous · Answer

Well first find the slope, using the following formula, since you're given two points: $$m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} }$$ where your coordinates represent $$(x_1,y_1)~~\text{and}~~(x_2,y_2)$$
Once you manage to get that, plug in m and your first coordinates in the point - slope form: $$y-y _{1}=m(x-x _{1})$$ do some little algebra and eventually you will have slope - intercept form $$y=mx+b$$

you don't have to do it this way, but I think it's good practice anyways.

b = y - intercept where the line crosses the y - axis

anonymous · Answer

is it y=7x

anonymous · Answer

$$
\frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_2-x_1}
$$

anonymous · Answer

Yes
