Can someone help me with this please?

29.) This is simply interpreting the linear function.
The function:
96+2.1x
a.) The 96 is what you start with from the beginning. So, we know Rachel weighed 96 ounces when she was born.
b.) Again, interpretation. The 2.1 is the slope, or the change in the line. So we know that Rachel gains 2.1 ounces each day.
30.) For this one, you just have to plug 9 into the equation for x.

The temperature on a particular day started at –13°F. It rose steadily by 3° each hour. The function y = –13 + 3x models the tem

The function you're given is in point-slope format, which is one of the easiest ones to graph. The basic form of the format is;

y=ax+b

Where a is the slope and b is the y-intercept.

As you can see, in y=-13+3x, the positions of a and b are switched, but it is essentially the same question.

From here we can tell that the y-intercept is -13, meaning that there is a point on the line that rests at (0,-13)

To find the other points, we can do rise-over-run using the slope of 3 given to us. What happens here is that for every 1 unit you go to the right (positive), you rise 3 units up.

For example, if we perform this on the y-intercept (0,-13):

(0+1, -13+3)
(1,-10)

With these two points, you can graph the line representing the temperature.
