Where does the line y=6x-7 cross the y-axis

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

The chs baseball team was on the field and the batter popped the ball up. the equation b(t)=80t-16•16+3.5 represents the height of the ball above the ground in feet as a function of time in seconds. how long will the catcher have to get in position to catch the ball before it hits the ground? round to the nearest second

Give me the equations of two lines that have the same slope but are not parallel.
