WHAT IS THE SLOPE OF THE LINE PASSING THROUGH THE POINTS (-2, -7) AND (3, 5)?????? PLZ ANSWER QUICKLY!!​
jarptica [38.1K]

Answer:

The slope of the line with points A(-2, -7) and B(3,5)  is  m =  (12/5).

Step-by-step explanation:

The two pints are given as A(-2, -7) and B(3,5)

Slope of a line with points (a,b) and (c,d) is given as

m =( \frac{d -b}{c-a} )

So, here the slope of line AB is

m =( \frac{5 - (-7)}{3 - (-2)} )  = \frac{5+ 7}{3 +2}   = \frac{12}{5}

or, m = 12/5

Hence, the slope of the line with points A(-2, -7) and B(3,5)  is (12/5).

The expressions a(8<img src="https://tex.z-dn.net/?f=x" id="TexFormula1" title="x" alt="x" align="absmiddle" class="latex-formul
amid [387]

Answer:

The expressions a(8x+7) and 4x + 3.5 are equivalent

Therefore, according to the above problem the equation is :---

a(8x + 7) = (4x + 3.5) \\ 8ax + 7a = 4x + 3.5

By comparing the term, we get

8ax = 4x \\ 8a = 4 \\ a =  \frac{4}{8}  \\ \boxed{a = \frac{1}{2} }

and,

7a = 3.5 \\ a =  \frac{3.5}{7}  \\  \boxed{a =  \frac{1}{2} }

<h3>The value of "a" is <u>1/2</u>.</h3>
