We are told that she drove 3 times as many miles in March as she did in January. This means that to get the number of miles she drove in January, we divide the number of miles she drove in March by 3:
900 / 3 = 300 miles
We are also told that she drove 4 times as many miles in February than January. This means that to get the number of miles she drove in February, we multiply the number of miles she drove in January by 4:
We need to use the Point slope formula to find the slope so we label (2 , -8);(-1 , 16) subtract x1 y1 x2 y2. y2-y1/x2-x1 16-(-8)/-1-2 = 24/-3 = -8 meaning the slope of this line is (-8)
