Braden has 10 red model cars, which are 2/5 of the total number of cars in his collection. how many cars does braden have in his collection?

a) 4
b) 10
c) 25
d) 50

25 cars, because if 10 cars = 2/5 of his collection that means 5 cars are 1/5. Since 1/5 x 5 = 1, that means there are 25 cars in his collection. (5x5 = 25)

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
