How do you graph the equation y = 2x + 3?

it has a y intercept of 3 therefore, it needs to pass the y axis through 4 3 and it has a gradient of 2 so you would start at the 4 on the y axis go across 1 and go up and keep doing it. Or cu could

Switch numbers from -2 to 2 into x into the equation to get x and y co-ordinates and then you could plot it. So it would be

when x is -2, y is -1  (-2,-1)

when x is -1, y is 1   (-1, 1)

when x is 0, y is 3    (0,3)

when x is 1, y is 5    (1,5)

when x is 2, y is 7     (2,7)

2 is the final ! : )

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
