Use the image to answer the question.

An illustration shows a coordinate plane with four quadrants. The x-axis and y-axis both range from negative 6 to 6 in one unit increments. A downward slanting line is graphed on the coordinate plane. The line passes through points plotted at left parenthesis 0 comma 3 right parenthesis, and left parenthesis 5 comma 1 right parenthesis.

Determine if the given graph is the graph of the function y=−25x+3. Enter 1 for yes. Enter 2 for no.

To determine if the given graph is the graph of the function y = -25x + 3, we need to compare the slope and y-intercept of the function with the given points.

The slope of the function y = -25x + 3 is -25. The slope of the line passing through the points (0,3) and (5,1) can be calculated as (1-3)/(5-0) = -2/5, which is not equal to -25.

Therefore, the given graph is not the graph of the function y = -25x + 3. Enter 2 for no.
