There is not a line shown above, but to solve this you would need the opposite and reciprocal slope and a y-intercept of 0.
To get an opposite and reciprocal slope, you simply flip the fraction and change the sign. So, if the original slope was 3/4, the new one would be -4/3. <span />
Multiply 8 by both numbers in the parentheses. -8x7 - 8x(-3.2) You should end up with -56 + 25.6 Next you add those two numbers and you end up with 30.4.
