\huge\text{Hey there!}



\large\text{Slope of a line formula is: }\mathsf{(y_2 - y_1)/(x_2 - x_1) = slope}

\large\text{Which simply translate to: }\mathsf{(rise)/(run) = slope}


\large\text{Or even this: }\mathsf{(\triangle_y)/(\triangle_x)}


\large\text{Let us label your information, so we can know what your equation}\\\large\text{should look like:}


\mathsf{y_2 = 10}\\\\\mathsf{y_1 = 7}


\mathsf{x_2 = -1}\\\\\mathsf{x_1 = -7}



\large\text{Your equation: }\mathsf{(10 - 7)/(-1 - -7) = slope}


\large\text{Solving:}


\mathsf{(10 - 7)/(-1 - -7) = slope}


\mathsf{(10 - 7)/(-1 + 7) = slope}


\mathsf{(3)/(6) = slope}


\mathsf{(3/1)/(6/2) = slope}


\mathsf{(1)/(2) = slope}


\huge\text{Therefore, your answer should be: \boxed{\mathsf{Option\ A. \ (1)/(2)}}}\huge\checkmark



\huge\text{Good luck on your assignment \& enjoy your day!}
