y = m x + C, where m is the slope and c is the intercept on the y axis. Plugging in the values of m and C, we get: y = 0 x + 10 = 0 + 10 = 10. Therefore, y = 10.
To get the result we can use knowledge that reading is 2 times longer than HW. To find this value we just have to multiply 42 times 2 so 40*2=80 Its 1 hour and 20 min - its the result
