Answer:

The equation in the standard form is

y+2x=5

Step-by-step explanation:

Given the points

  • (6, -7)
  • (4, -3)

Finding the slope between (6, -7) and (4, -3)

\left(x_1,\:y_1\right)=\left(6,\:-7\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-3-\left(-7\right)}{4-6}

m=-2

As the point-slope form is defined as

y-y_1=m\left(x-x_1\right)

substituting the values m = -2 and the point (6, -7)

y-y_1=m\left(x-x_1\right)

y-\left(-7\right)=-2\left(x-6\right)

Writing the equation in the standard form form

As we know that the equation in the standard form is

Ax+By=C

where x and y are variables and A, B and C are constants

converting the equation in standard form

y-\left(-7\right)=-2\left(x-6\right)

y+7=-2\left(x-6\right)

subtract 7 from both sides

y+7-7=-2\left(x-6\right)-7

y=-2x+5

y+2x=5

Therefore, the equation in the standard form is

y+2x=5

The first step in the process for factoring the trinomial x2-3x - 40
Alexxx [7]
We need two numbers that when multiplied will give you -40 and when added will give you -3:
(x+5) (x-8) this is your answer. And you want to know the process Here it goes. And attached is a chart I made you so you can visually see what this process is telling you:
1) identify a,b, and c in the trinomial ax^2 + bx+c (in your case it's 1x^2-3x-40= x^2-3x-40)
2) write down all factor pairs of c (numbers that multiplied produce -40)
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials

since the 1950's, air pollution and robberies have increased. the conclusion that air pollution causes robberies is
dlinn [17]
Had to look for the options and here is my answer.
Starting from the 1950s, both robberies and air pollution has increased and the conclusion that we can say regarding this increase is NOT JUSTIFIABLE. It is not justifiable because population is a different variable and they are not directly related to each other. Hope this helps.
