#### Explanation:

Given a slope

#y - y_1 = m(x-x_1)#

In our example,

#y - 1/10 = -1/25(x-7/5)#

Expanding and rearranging, this can be expressed as:

#y = -1/25x+39/250#

which is in slope intercept form:

#y = mx+b#

with

graph{(y - 1/10 + 1/25(x-7/5))(x^2+(y-39/250)^2-0.0017)((x-7/5)^2+(y-1/10)^2-0.0017)=0 [-1.76, 3.24, -1.17, 1.33]}
