What is f congruebt to i think it is congruent
Answer:
B. No the ordered pair does not satisfy the equation
Step-by-step explanation:
y = -9x - 2
Substitute the point in and see if it is true
-37 = -9(4) -2
-37 = -36 -2
-37 = -38
This is not true so the point is not a solution
The tool I used for modellin is MS Excel. As you on the left side of the picture, I tabulate the x and y coordinates with respect to their columns. Then, I plotted it using the scatter plot graph. In this type of graph, only plots are drawn on the Cartesian plane. Next, I created a trendline as represented by the blue dashed line. There are options to the degree of your trendline: linear, polynomial or exponential. The closes fit is the polynomial with a degree of 2. An option is listed there in displaying the equation. The equation modelled by regression through data fitting is:
y = x² - 4x+1

Answer:
A. y=-0.5x-2.5
Step-by-step explanation:
To figure out the equation of a line, use the formula y=mx+b, where x and y are the co-ordinate values, m is the slope and b is the y-intercept (where the line cuts the y-axis).
The slope, m, is calculated by dividing the y-difference (in this case, -2.5) by the x-difference (5): -2.5/5 = -0.5
From the diagram, we can see the line cuts the y-axis at (0,-2.5). Therefore b=-2.5
Sub in our values to get: y=-0.5x-2.5
