can someone help please? medal and fan?

slope intercept form: $\tt{y=\color{blue}{m}x+\color{red}{b}\ \color{blue}{m=slope} \ \color{red}{b=y-intercept} }$

pooja195 · Answer

First find the slope
$$\LARGE \frac{y_2-y_1}{x_2-x_1}=slope$$

anonymous · Answer

To find the slope, use the slope formula which is m= (y2-y1)/(x2-x1). In this case the slope is 2.

anonymous · Answer

The plug it into the slope intercept formula, which is y = mx+b, so you get 14=2(2) + b, solve for b and you get 3.5 or 7/2.

anonymous · Answer

so with the 2 what should I do then?

anonymous · Answer

sorry took me a bit to write it out, wanted to make sure I got it right :)

mehek14 · Answer

put 2 for m $\tt{y=2x+b}$
now choose one of the 2 ordered pairs
