Y = kx is the direct variation equation Fill in the x and y given to solve for k. Then write a new equation with k to solve for future equations. 7 = 2 * k 7/2 = k y = 7/2 x 21 = (7/2) x (2/7)(21) = x 6 = x
<span>If y varies directly with x, the formula of the equation is y=ax, where a is a constant. y=ax (21)=a(7) a=3 y=ax y=(3)(-1.66) y=-4.98, x=-1.66 If y varies inversely with x, the formula of the equation is y=a/x, where a is a constant y=a/x 9=a/2.5 a=22.5 y=22.5/x y=22.5/-0.6 y=-37.5 I hope this helped! =) I hope you didn't mind but I got this from a website called: answers.yahoo.com but I got your answer. </span>

The slope-intercept form of a linear equation is y=mx+b. m being the slope (part one of name) and b being the y-intercept (part 2 of name).
Hey!
Answer:
4/1
Step-by-step explanation:
The multiplicative inverse of a number is the reciprocal of it. (a/b → b/a). Basically you divide 1 by the other number. (1 ÷ 1/4 = 4 or 4/1).

Step-by-step explanation:
42 × y = 1 × 3024
42y = 3024
42y ÷ 42 = 3024 ÷ 42
y = 72
