He earns 31 points when he collects 2 yellow gems and 3 blue gems. He earns 23 points when he collects 2 blue gems and 3 red gems. When Brian collects 2 red gems, 2 yellow gems, and 2 blue gems, how many points does he earn?

Use the point-slope form to write an equation of the line with the given slope and point. Then write the equation in slope-intercept form. slope 4 , passes through \( (4,6) \)

Verifique se a equação abaixo é ou não é uma proporção \( \frac{2-2 x}{3 x}=-\frac{1}{3} \)
