Answer: y = 3x + 1
let me know if you want to see the math
Answer:
I think it is but not 100% sure
Step-by-step explanation:
From the table of values you can see the each y value is 3 times the x value.
This would be the slope of the line of graphed.
The equation is y = 3x
Answer:
99 students
Step-by-step explanation:
To get this answer, you need to add all of the numbers up because the 3rd graders and 4th graders are joining the 2nd graders. 27+43=70. 70+29=99.
Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.
