Answer:
See below
Step-by-step explanation:
Minutes Temperature
0 -2
1 1
2 3
3 4
4 5
5 -4
6 2
7 -3
Minutes should be graphed on x - axis as it repeatedly increases by 1 and seems to be independent. (Remember the independent variable is on x-axis). The axis increment should be one as told before, that the terms are increasing by 1.
Now, Temperature should e graphed on y-axis because it seems to depend on Minutes. The axis increment should also be 1 for this as although, it not increasing by 1 but still at some points increases by 1. So, the axis increment should be 1 for Temperature.
Answer:
<h3>The option C) 15 s is correct</h3><h3>Therefore the maximum height it reaches in <u>15 seconds. </u></h3>
Step-by-step explanation:
Given equation is 
Given that a projectile is thrown upward so that its distance above the ground after t seconds is
<h3>To find how many seconds does it reach its maximum height:</h3>
"The standard form of a parabola's equation is expressed as :
.
If 
, then the parabola opens upwards;
if 
the parabola opens downwards."
The maximum height is the vertex of the parabola which is 
.
Comparing the given equation with the standard form of parabola we get
the values of a=-13 , b=390 and c=0
The maximum height in 
.
Substitute the values we get
<h3>∴ t=15 s</h3><h3>∴ The option C) 15 s is correct.</h3><h3>∴ the maximum height is the vertex of the parabola, at t reaches in 15 seconds. </h3>

If the question is to find the slope-intercept form of both lines, here's the answer:
Both lines pass through the point (-3,-4), so we can use these coordinates in both equations. The slope-intercept form is represented by y=mx+b, with m the slope, b the intersection of the line with Y'Y for x=0, y and x the coordinates of a point.
Let's first apply all these for the first line, with a slope of 4.
y = mx + b
y=-3; x=-4; m=4. All we need to do is find b.
-3 = 4(-4) + b
-3 = -16 + b
b=13
So the equation of the first line is y= 4x + 13.
Now, we'll do the same thing but for the second line:
y=-3; x=-4; m=-1/4, and we need to find b.
-3 = (-1/4)(-4) + b
-3 = 1 + b
b= -4
So the equation of the second line is y=(-1/4)x - 4
Hope this Helps! :)
Use y=mx+b
m = 4
x = 0
y = -1
-1 = (4)(0) + b
