Graphing proportional relationships: unit rate - Khan Academy In proportional relationships, the unit rate is the slope of the line Changes in x lead to steady changes in y when there's a proportional relationship We can use the unit rate to write and graph an equation of the line that represents the relationship
Graphing proportional relationships from a table - Khan Academy Let's graph a proportional relationship from a table of values The graph of a proportional relationship is a line, so we can graph from any 2 points in the table The slope of the line represents the unit rate, so changes in x and y values determine the slope
Graphing proportional relationships from an equation Let's graph the equation y = 2 5x For every increase of 1 in x, y increases by 2 5 We call this the "unit rate" or "slope" The graph shows a proportional relationship because y changes at a constant rate as x changes and because y is 0 when x is 0
Proportional relationships | 7th grade math | Khan Academy Learn all about proportional relationships How are they connected to ratios and rates? What do their graphs look like? What types of word problems can we solve with proportions?
Graphing proportional relationships (practice) | Khan Academy Practice graphing a line that represents a proportional relationship Use the Tab key to move through the interactive elements in the graph When an interactive element has focus, use Control + Shift + Arrows to move it
Graphing proportional relationships from a table (video) | Khan Academy Let's graph a proportional relationship from a table of values The graph of a proportional relationship is a line, so we can graph from any 2 points in the table The slope of the line represents the unit rate, so changes in x and y values determine the slope
