Graph the set of data
{(1,7),(-2,1),(3,13),(-4,-3),(0,5)}
Answers are
Y=0,9x+8.6
Y=2/5x=-2
Y 5/2x+5
Y=5
Thanks
Try actually plugging in the points to see which equation fits!
Or, arrange the points from left-to-right:
(-4,-3) (-2,1) (0,5) (1,7) (3,13)
as x changes by 2, y changes by 4 (except for the last one - typo?)
It appears that none of the choces will work.
To graph the set of data {(1,7),(-2,1),(3,13),(-4,-3),(0,5)}, we need to plot each point on a coordinate plane.
1. Start by drawing the x-axis and y-axis on the coordinate plane, representing the range of values for x and y.
2. Now, let's plot the given points:
- The point (1,7) means x=1 and y=7. So we plot the point (1,7) on the coordinate plane.
- The point (-2,1) means x=-2 and y=1. So we plot the point (-2,1).
- The point (3,13) means x=3 and y=13. So we plot the point (3,13).
- The point (-4,-3) means x=-4 and y=-3. So we plot the point (-4,-3).
- The point (0,5) means x=0 and y=5. So we plot the point (0,5).
3. After plotting all the points, you will notice that they do not form a straight line. Therefore, none of the given answers is a linear equation that can represent all the points.
However, if you would like to find the equation of a line that best fits these points, you can use various methods like the least squares regression line to obtain the best linear approximation.
