this still aint makin sense

zepp · Answer

We have a point at $\large(8,-1)$ and the slope is $\large -\frac{1}{4}$

anonymous · Answer

si

zepp · Answer

We'll use the point-slope form and plug everything in.

$$\large (y-y_1)=m(x-x_1)\\large y-(-1)=-\frac{1}{4}(x-8)$$

zepp · Answer

And you simply distribute!

$$\large y+1=-\frac{1}{4}x+2$$

zepp · Answer

Slope-intercept has the form $\large y=mx+b$

$$\large y=-\frac{1}{4}x+2-1\
\large y=-\frac{1}{4}x+1$$
