Write an equation of a line that is perpendicular to y = 2/3 x + 8 and has a y-intercept of

Otrada [13]

Answer:

y = -3/2x + 2

Step-by-step explanation:

Since you know it has a point at (0, 2) - the y intercept, put those values into the equation and solve. To be perpendicular it seems the reciprocal of the slope with the opposite sign, so 2/3 is the original slope, and -3/2 becomes the new slope.

y = 2/3x + 8 becomes

2 = -3/2(0) + b We substitute in the x and y values, but we have to figure out what the last number will be.

2 = 0 + b

b = 2

So put the whole equation together

y = -3/2x + 2

Answer:

Step-by-step explanation:

To find the constant of proportionality between y and x, divide $\frac{y}{x}$ for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
