25. Because (30/50)/(2)= 15/25
15= cars washed
25 = lawns mowed
The slope is 1/2 and the y-intercept is 3/2. those are the steps to graph the equation.
Answer:
If Anne’s age is represented by the variable a then express Jenny’s age in terms of a if Jenny is three years less than half of Anne’s age
Answer:
15
Step-by-step explanation:
Rate of change or slope or gradient of a line passes two points (x1, y1) and (x2, y2) could be calculated by:
(y2 - y1)/(x2 - x1)
=> Rate of change of the line passing (1,15) and (3,45):
(45 - 15)/(3 - 1) = 30/2 = 15
