Answer:
x= -18
Step-by-step explanation:
We want to isolate x ( move everything to the other side of the equation)
-7 = -1 + x/3
-6 = x/3
x= 3*-6
x= -18
21
is what I got on my calculator
That question is impossible because we don’t know what we are trying to solve for it has to be x or y in this scenario it can’t be both we need one to find the other
The slope-intercept form:

m - slope
b - y-intercept
We have the slope
and the point (10, 4).
Substitute the value of slope and the coordinates to the equation of line:

Answer: 
Answer:
90% of the variation in the dependent variable is explained by the independent variable.
Step-by-step explanation:
We are given the following in the question:
coefficient of determination = 0.9
We have to find the percentage of variation in the dependent variable explained by the variation in the independent variable.
Coefficient of Determination:
- The coefficient of determination is a measure that explains and predicts the dependent variable.
- It explains the variation in the dependent variable caused by the independent variable.
- The coefficient of determination, also known as the R squared value and is obtained by squaring the coefficient of correlation.

Thus, 90% of the variation in the dependent variable is explained by the independent variable.
