Write the equation of the line that passes through the points (-3,2) and (-1,6)

Mathematics

Answer:

y=2x+8

Step-by-step explanation:

An equation that is most suitible for this kind of problem is the slope intercept form with is y=mx+b.

m=slope

b=y-intercept

1: Find the slope

Use the formula y2-21/x2-x1

6-2/-1-(-3)=4/2=2

m=2

2: Find the y-intercept

For me personally, I think it is easiest to just graph the points, draw the line, then find where the line meets the y-axis.

b=8

<u>y=2x+8</u>

Sam is observing the velocity of a car at different times. After three hours, the velocity of the car is 53 km/h. After six hour
almond37 [142]
To answer the question above, determine the velocity of the car at time zero. To do such, determine the increase in velocity every hour (acceleration). 

                                     a = (62 - 53) / (6 -3) = 3 km/ h^2

Calculate for the initial velocity (v) by using either of the velocities paired with the corresponding time,
        
                                     v = 53 km/h - (3 km/h^2) x 3 h = 44 km/h

The equation is <em>y = 44 + 3x</em>. Where x is the time in hours, y is the velocity in km/h.

What are the domain and range of each relation?
torisob [31]

Order pairs  given coordinates on the graph: {(−3, 1), (−3, -4), (−1, 1), (1, -1), (4,4)}.


We need to find the domain and range.


<em>Domain of the order pairs are x values of each coordinate and range is the y values of each given coordinate.</em>


Each first value of order pair are the x values and each second value of each order pair are the y values.


In the given coordinates on the graph (−3, 1), (−3, -4), (−1, 1), (1, -1), (4,4), we can see first values are { -3,-1, 1, 4}


and we can see second values are { -4, -1, 1, 4}.

<h3>Therefore, Domain : { -3,-1, 1, 4} and </h3><h3>Range : { -4, -1, 1, 4}</h3>
