The equations are 6.5x + 8.3y + 7.1 = 0 and
-7.2x + 3.4y - 6.6 = 0. Find the slope and x and y intercepts of each equation.

For the first equation I got the x intercept as -10.92 and y intercept as -8.55 but I can't figure out the slope.

For the second one i got the x as -.915 and y as 1.94. but i can't get the slope either.
