Choose the true statement for the following graph. Direct link to aubrey.cobb's post Sal you are a life saver, Posted a month ago. Linear . goes through the origin. d) It is concave down. The line would look something like this. So it's a linear relationship, but it does not go through the origin, so it's not proportional. This means the y-coordinate to a point on the left of the y-axis must be mirrored as the same on the point to the right. Fusce dui lectus, congue vel laoreet ac, dictum vitae odio. The reason this works is that points on a vertical line share the same x-value (input) and if the vertical line crosses more than one point on the graph, then the same input value has 2 different output values (y-values) on the graph. go through the origin, but notice, it's not a line. They are used because the benefits to human health are believed to outweigh the environmental costs. values, look at the ratios, and the ratios always To understand this, click here.
