Answer:
It is answer B
Step-by-step explanation:
The reason is, A there is a trend going on, the points are all relatively in the same place, going in the same direction. C it is a positive trend, all the points are relatively in the same place all going up. While in B, the points are scattered all over the graph. Hence the name, scatter plot, or scatter graph.
The last one is the answer. GD is similar to MJ, and DE is similar to JK. While DE is similar to ML as well, it is more so to JK because they are facing the same way
Answer:
9x+2y=-10
Explanation:
First, we would need to organize the information given into slope-intercept form.
Slope-intercept form: y=mx+b
Here’s what the variables mean:
Y=the y coordinate
M=the slope
X=the x coordinate
B=the y-intercept (the point on the line that intercepts the y-axis)
When a linear equation in slope-intercept form is complete, the x and y variables are left just as they are. Knowing this, we just have to plug in the values given for the coordinate and solve for b, the y-intercept.
(-2,4),
y=mx+b
4=m(-2)+b
4=-2(-9/2)+b
4=9+b
Subtract 9 on both sides
4-9=9+b-9
-5=b
Awesome! Now, we know that the equation in slope-intercept form is:
y=-9/2x-5
To organize it into standard form, we need to move some things around.
Standard form: Ax+By=C
(A, B and C don’t have any kind of direct interpretation on a graph.)
y=-9/2x-5
Move the x variable to the other side
9/2x+y=-9/2x-5+9/2
9/2x+y=-5
It may look like we’ve finished here, but A, B and C need to be integers, meaning we cannot have any fractional values in these places.
9/2x+y=-5
Multiply both sides by 2 since it is the denominator
9x+2y=-10
I hope this helps! Please comment if you have any questions.
