How can you tell before you divide 425 by 9 that the first digit of the quotient is in the tens place?

(-9,7), (6,2) write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form

Express the following as a function of a single angle, cos(60) cos(-20) - sin(60) sin(-20)

Plzzzz i beg u asap ! what is the equation of this graphed line? enter your answer in slope-intercept form in the box.
