Can someone help me with (a) and (c)? Thanks! ;D
BaLLatris [955]

Answer:

Step-by-step explanation:

a) Mark any two points in line a

(0,7)  ; (5,-3)

Find the slope

slope = y2 - y1 /x2-x1

=\frac{-3-7}{5-0}\\\\=\frac{-10}{5}\\\\=-2

Equation: y-y1 = m(x-x1)

y - 7 = -2(x - 0)

y - 7 = -2x

y = -2x + 7    --------> line a

c) equation of line b

(2,-1);  slope = -2  {as b line is parallel to line a}

y - y1 =m(x-x1)

y -(-1) = -2*(x - 2)

y + 1 = -2x - 2*-2

y + 1 = -2x + 2

y = -2x + 2 -1

y = -2x +1   ------> equation of line b

What is the meaning of the t-intercept of the altitude graph? The y-intercept?
Gnom [1K]

Answer: Hello mate!

We know that you have a graph of y vs t, and we know that this is an "altitude" graph.

Then we can assume that the y represents the altitude, and t represents the time, and this graph shows the altitude of something as a function of the time.

the t-intercept means that the graph passes through the y-axis, this means that, in this point, y is equal to zero:

Then, at the t-intercept, we have y = 0, which means that at this time (where is the intersection) the altitude is equal to zero.

The y-intercept means that the graph passes through the y-axis, where t = 0

this is the initial value of the altitude, where t = 0 usually denotes the time where we start to measure.
