The temperature on a particular day started at –13°f. it rose steadily by 3° each hour. the function y = –13 + 3x models the temperature, where x is the number of hours and y is the temperature. graph the equation.

To graph this equation, which is just a line, you only need two points on it (any two, it does not matter)

y=-13+3x  so

y(0)=-13ex

y(1)=-10

so you now have two points, (0.-13) and (1,-10)

place a dot at each point and trace a line between them and extend that line as far as you wish in either direction.

All points to the left of zero on a horizontal number line are negative. a number line is a picture of a graduated straight line that serves as abstraction for real numbers. this number line can be extended to the left to represent numbers which are smaller than 0. such numbers are called negative numbersmark me brainliest
