Kakšni so prestopi za y = 2x + 3?

Odgovor:

# "x-intercept" = -3 / 2, "y-intercept" = 3 #

Pojasnilo:

# "da najdete prestreznike, kjer križ prečka" # #

# "osi x in y" #

# • "naj x = 0, v enačbi za y-prestrezanje" #

# • "Naj je y = 0, v enačbi za x-intercept" #

# x = 0rArry = 0 + 3 = 3larrcolor (rdeča) "y-intercept" #

# y = 0rArr2x + 3 = 0rArrx = -3 / 2larrcolor (rdeča) "x-intercept" #

graf {(y-2x-3) ((x-0) ^ 2 + (y-3) ^ 2-0.04) ((x + 3/2) ^ 2 + (y-0) ^ 2-0.04) = 0 -10, 10, -5, 5}
