Answer:
(2, -2) and (1,-3)
Step-by-step explanation:
The y-intercept means that the coordinate where the line touches the y-axis. In other words, the y value(-4) when x=0. The result is (0, -4). The y coordinate also can be used to fill c variable of y=mx + c
We have 2 coordinates now, (3, -1) and (0, -4), then we can find out the line equation. We need to find the slope (m), the formula will be:
m= y2-y1 / x2-x1=
m= -4 - (-1) / (0-3)
m= -3/-3= 1
The line equation is:
y= mx + c
y= 1x + (-4)
y= x-4
After you have the equation, you can try to test the point individually to find if any of them fit the equation. You can also draw a line on the graph and see if any point touches the graph.
Red dot is the two point we have, red line is straight line that made from both point, and blue point is the option. As you can see on the graph, the points that touch the line will be (2, -2) and (1,-3)
In Canada in 1998 the estimated number of households written in standard decimal notation is 3939000
<u>Solution:</u>
Given that in 1998 estimated number of households that owned 2 or more vehicles was
Need to represent the number in standard decimal notation.
In this case we need to move the decimal point based on the power of 10.
In our case power of 10 = 6.
Let’s first take a number without and add six zeros on right.
So we get 3.939000000
Now multiplying above number by means moving the decimal after 6 numbers from the current position, that means
That is 3939000 is required standard decimal notation of scientific notation number
