Answer:
A: 80
Step-by-step explanation:
As we know that the trend line is
, we can plug in x=3 in order to find out the estimated score for 3 hours of studying
![y=6.8x+60\\\\y=6.8(3)+60\\\\y=20.4+60\\\\y=80.4](https://tex.z-dn.net/?f=y%3D6.8x%2B60%5C%5C%5C%5Cy%3D6.8%283%29%2B60%5C%5C%5C%5Cy%3D20.4%2B60%5C%5C%5C%5Cy%3D80.4)
y=80.4 is closest to A: 80
Answer:
y = -5x + 2
Step-by-step explanation:
Slope-intercept form is written as y = mx + b.
m is the variable representing slope, how steep the line is.
b is the variable representing the y-intercept, when the graph hits the y-axis.
x and y, when substituted, tells you the points on the graph.
When writing the equation of a line, you need the slope and the y-intercept.
In y = mx + b, substitute m for -5 and b for 2.
y = -5x + 2
Answer:
1,3,4
Step-by-step explanation:
Answer:
A) Neither
Step-by-step explanation:
If two lines have same slope then they are parallel lines
If slope of line1* slope of line 2 = -1
The the two lines are perpendicular
In this question slope of line = 2\7
Slope of line 2 = 7\2
Hello :
the solution is : <span>(3, -1)
put x= 3 and y = -1
you have : 3-(-1) = 4 and 3+(-1) = 2 ..... right</span>
