SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Define a slope of positive and negative line
A slant asymptote, just like a horizontal asymptote, guides the graph of a function only when x is close to but it is a slanted line, i.e. neither vertical nor horizontal. A rational function has a slant asymptote if the degree of a numerator polynomial is 1 more than the degree of the denominator polynomial.
A line that slants up from left to right has a positive slope. A line that slants down from left to right has a negative slope. Horizontal and vertical lines also have a slope.
STEP 2: Answer the question
Hence, the answer is "The line slants up"
