Answer:
x = 142
Step-by-step explanation:
√x+2 - 15 = -3 (Given)
√x+2 = 12 (Add 15 on both sides)
x + 2 = 144 (Square both sides to get rid of the radical)
x = 142 (Subtract 2 on both sides)

Answer:
Slope is 9 and -2 is the y-intercept
Step-by-step explanation:
As an equation in slope-intercept form is written as y=mx+b where m is slope and b is its intercept on the y-axis.
If one writes a linear equation as a function of y, one can easily get slope which is coefficient of x and intercept, which is constant term.
As y= -9x is already in this form, we have its slope as -9 and intercept on y-axis is 0, that is if it passes through the line of origin.
