HELP PLEASE Find the slope of the linear model​

Take two values

31.5-27/1= 4.5

Hence slope is 4.5x

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
