Question

PLS HELP!!!
A line passes through (–7, –5) and (–5, 4).
a. Write an equation for the line in point-slope form.
b. Rewrite the equation in standard form using integers.

Answer 1

@Zepdrix Can you help ^_^

Answer 2

Since you are given two points you can find the slope between the two.

\(\Large\bf{slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}} \rightarrow \frac{4-(-5)}{-5-(-7)} \rightarrow \frac{9}{2}}\)

Once this is found you are now able to plug into point slope.

\(\large\bf{y-y_{1}=m(x-x_{1})}\)

\(\bf{(x_{1},y_{1}) \rightarrow first~point}\)

Remember that \(\bf{m}\) equals \(\bf{slope}\).

What is the equation?

Answer 3

so, y+5=9/2(x+7) for the point-slope form?

Answer 4

^ well done

now, for part b, you would distribute the 9/2 and then re-write the equation into Ax + By = C form
