1. This is a very easy question as you can just plug in 2 x-values and get the y-value, run a line through it, and you are done. 

For example,
x = 2t
x = 2(2) = 4
x = 2(3) = 6

Now, you know there are points at (2, 4) and (3, 6).

2. This one is a little tricky, but all it's saying is that it has a specified domain. The parametric equation only works for values -2 ≤ t ≤ 3. So, you can do the exact same thing, except your line will only exist for points through the x-values -2 and 3. Let's plug in numbers:

y = t + 5
y = -2 + 5 = 3
y = 1 + 5 = 6

Now you know that this line runs through (-2, 3) and (1, 6). Remember, your line starts at -2 and ends at 3. It can't go any further than that.

The slope of the line below is 1.write the point-slope equation for the line using the coordinates of the labeled point.
Oliga [24]

Answer:

y-4=(x-11) or y=(x-11)+4

Step-by-step explanation:

We know that the slope of the line is 1, so we can write it in terms of any two points belonging to the line, as per the difinition of slope:

slope=\frac{y_1-y_0}{x_1-x_0} \\1=\frac{y_1-y_0}{x_1-x_0}

We can use instead of (x_1,y_1) any general point (x,y) on the line, and for (x_0,y_0) the point we are interested in: (11,4)

That way the slope can be written as:

1=\frac{y-4}{x-11}

Next we can solve for y if this format is the one your instructor prefers:

1=\frac{y-4}{x-11}\\1(x-11)=(y-4)\\(x-11)+4 =y
