why is the slope of the linear model significant why are the slopes and intercepts for trend lines similar can you t test two linear models to check if they are substantially different what is the difference between t test and trend line how does one comparing two trend lines do how is the relationship between trendline and intercept calculated in dslr how is the trend line different from the model when do you need to compare two regression models how to compare two linear models can you compare two trend lines with a linear model can you measure the difference between a model and a trend can the two trend lines intersect how to compare two different rsa models using trend lines do you compare two models why are the intercepts of the two independent variables substantially different from the slopes of both trend lines? how do you find the difference between the two linear models and find their independent variable when two trend lines are compared, do the slopes and intercepts overlap what is the t-test to compare a trend line vs independent variable? how to compare two trends using the t test what is the difference between a linear model and a trend line
