Which statement is true?

(a)if the x-intercept of a line is given by (0, b), b can never equal zero.
(b)a line of x = a (where a is not zero) cannot have a y-intercept.
(c)if the y-intercept of a line is given by (a, 0), a can never equal zero.
(d)a line with a zero slope cannot have a y-intercept.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
