Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. To turn x+2y=-4 into the form you are asking for, you have to isolate y. The first step to accomplishing that is to subtract x from both sides.
2y=-x-4

Next, you divide both sides by 2 and you'll have slope-intercept form!!!
y=-1/2x-2

The slope is -1/2 (remember, rise/run) and the line intersects the y-axis at point (0,-2).

X + 2y = -4
-x            -x

2y   = -x - 4

Divide all by 2

y = -x/2 - 2

y = (-1/2)x - 2

Anyone please help me pleaseeee

R = { (x,y): 3x-y=0 }

The condition is 3x=y so that's not going to be any of these things.

R is reflexive if (x,x)∈R for all x.   Let's check.

3x - y = 3x - x = 2x ≠ 0  necessarily.   NOT REFLEXIVE

R is symmetric if (x,y)∈R → (y,x)∈R.   Let's check.

(x,y)∈R  so

3x-y = 0

y  = 3x

Is  (y,x)∈R.  That would be true if 3y-x=0

3y - x = 3(3x) - x = 8x ≠ 0 necessarily NOT SYMMETRIC

R is transitive if (x,y)∈R and (y,z)∈R → (x,z)∈R.   Let's check.

3x-y = 0  so y=3x

3y-z = 0 so z=3y = 9x

3x - z = 3x - 9x = -6x ≠ 0 necessarily   NOT TRANSITIVE

What is the answer to thiss
lana [24]

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression.  So let's plug in the values and solve.

<u>Plug in the values</u>

  • m^2 + 5
  • (9)^2 + 5

<u>Factor out the exponent</u>

  • (9*9) + 5
  • 81 + 5

<u>Combine</u>

  • 86

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
