Question

the line through (1,7) and (-6,7) in point-slope form?

Answer 1

point slope form is:
\[y-y_1=m(x-x_1)\]
with
\[m=\frac{\Delta y}{\Delta x}\implies \frac{y_2-y_1}{x_2-x_1}\]
you are given two points in the terms:
\[(x_1,y_1);(x_2,y_2)\]
plug your points into the m= equation to solve for it, then plug your points and slope in to the general form.

Answer 2

but the slope for those coordinates is 0

Answer 3

so the answer would be y-7=0(x-1) ?
