Apakah percikan x dan y -5x + 2y = -20?

Jawapan:

X-intercept = (4,0)

Y-intercept = (0, -10)

Penjelasan:

Untuk x-intercept, sub # y = 0 #

iaitu # -5x + 2 (0) = -20 #

# -5x = -20 #

# x = 4 # (4,0)

Untuk y-intercept, sub # x = 0 #

iaitu # -5 (0) + 2y = -20 #

# 2y = -20 #

# y = -10 # (0,-10)
