Question

Find the value of r so that the line that passes through them has the given slope. (3,5)(-2,7) slope = -1

Answer 1

We have to find the equation of a line with a slope m=-1 and pass through the point (3,5).

Then we will check if it goes through the point (-2,7).

We can write the line equation in slope-point form:

`y-y_0=m(x-x_0)`

Then, it becomes:
