x = 5.y.z so 5.10.12 = 600
To find the y-intercept, plug 0 in for x: 3y = -12 y = -4To find the x-intercept, plug 0 in for y: 2x = -12 x = -6The y-intercept is y = -4, and the x-intercept is x = -6.

y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
x equals -12 and y equals 1/4 of -12, so y = -3.
y = cx when x = 8, y = 12 so that 12 = 8c which gives c = 12/8 = 1.5
x = 24
x = 5.y.z so 5.10.12 = 600
Insufficient information. What is x when y = 12?
y/x is a constant; so first of you can solve for this constant. y/x=6/-3, or y/x=-2 y/4=-2 y=-8
To find the y-intercept, plug 0 in for x: 3y = -12 y = -4To find the x-intercept, plug 0 in for y: 2x = -12 x = -6The y-intercept is y = -4, and the x-intercept is x = -6.
