What is the x - and y - intercepts of -3y = 7x - 21
frozen [14]

Answer: x-intercept = (3,0); y-intercept = (0,7)

Step-by-step explanation:

-3y = 7x - 21

y = -7/3 x + 7 (divide both sides by -3)

y-intercept = (0,7) (y = mx + b; b is always y-intercept)

0= -7/3 x + 7 (plug in 0 for y to get x-intercept)

-7/3x = -7 (subtract 7 from both sides)

x = 3 (divide both sides by -7/3)

x-intercept = (3,0)
