Find an equation of the line that passes through the given points. (let x be the independent variable and y be the dependent variable.) (−1, −2) and (7, −6)

In standard form, your answer would be y = -0.5x - 2.5.

Step-by-step explanation:

If you put the points into the formula, (y2-y1)/(x2-x1), then you will be able to find the slope which is -0.5. Then, all that is needed is to find where the line that passes through both points passes through the y axis, which is -2.5.

step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
