The linear equation that best models this data is y=0.216x + 32.575
Part A: The slope of the line is
0.216
and the y-intercept is

b = 32.575

Step-by-step explanation:

The y-intercept is 32.575.

(-5,-28)

i graphed to on desmos.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
