Write the linear equation in slope intercept form 1,3 and -3,-5

oksian1 [2.3K]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points through which the line passes:

$(x_ {1}, y_ {1}) :( 1,3)\\(x_ {2}, y_ {2}): (- 3, -5)$

We found the slope:

$m = \frac{y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

Substituting we have:

$m = \frac {-5-3} {- 3-1} = \frac {-8} {- 4} = 2$

Thus, the equation is of the form:

$y = 2x + b$

We substitute one of the points and find the cut-off point:

$3 = 2 (1) + b\\3 = 2 + b\\3-2 = b\\b = 1$

Finally, the equation is:

$y = 2x + 1$

ANswer:

$y = 2x + 1$

Which is the total number of valance electrons in a sulfide ion in the ground state

Virty [35]

believe the answer is 8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.

A person who is 1.5 meters tall casts a shadow that is 8 meters long. The distance along the ground from the person (N) to the f

neonofarm [45]

1.) 1.5m/8m= fg/32m
2.) 1.5 (32)= 8m * fg
3.) 1.5 (32)/8m= fg
4.) 6m = fg

Im pretty sure that's right

Sloane kicked a soccer ball at a speed of 56 feet per second. If the ball never leaves the ground, then it can be represented by

aksik [14]

Answer:

Third option: $t=3.5\ seconds$

Step-by-step explanation:

Given the function:

$H(t)=-16t^2 +56t$

Since the ball never leaves the ground, you need to substitute $H(t)= 0$ in the function in order to determine the time the soccer ball traveled:

$0=-16t^2 +56t$

Factorizing, you get:

$0=-8t(2t-7)$

Then:

$0=-8t\\\\t=0\ seconds\\\\\\\\0=2t-7\\\\7=2t\\\\t=3.5\ seconds$

Therefore the time the ball traveled was:

$t=3.5\ seconds$
