7x+2y>-5(-1,1) Determine whether the ordered pair is a solution of the linear inequality

Mathematics
1 answer:
boyakko [2]2 years ago
7 0

Answer:

  • No

Step-by-step explanation:

<u>Given inequality:</u>

  • 7x + 2y > - 5

<u>Verify if (-1, 1) is correct:</u>

  • 7(-1) + 2(1) > - 5
  • - 7 + 2 > - 5
  • - 5 > - 5

False inequality, it is not the solution

which answer choice explains the pattern for how to find the slope using an equation in standard form?
Liono4ka [1.6K]

Question is using standard formula ax+by=c to find the slope by converting into slope intercept form y=mx+b

so we also need to convert ax+by=c into y=mx+b as shown below:

ax+by=c

ax+by-ax=c-ax

by=-ax+c

divide both sides by

y=-\frac{a}{b}x+\frac{c}{b}

Now compare it with y=mx+b, we get

m=-\frac{a}{b}

So using values of a and b, we can find the slope


compare given equation -5x+2y=15 with ax+by=c, we get:

a=-5, b=2

Now plug both into above formula

m=-\frac{a}{b}

m=-\frac{-5}{2}

m=\frac{5}{2}


Now matching these details with given choices we find that THIRD choice is the final answer.
