Write an equation in standard form for the line that passes through the given points.

Agata [3.3K]

So, pretend this is your x-axis and y-axis:

(-2,7) • I

I • (2, 5)

_________________I____________________

TO GET FROM POINT (-2, 7) TO POINT (2, 5), WE MOVE DOWN 2 AND OVER 4, SO THE SLOPE IS -1/2. IF WE FOLLOW THAT SLOPE AND MOVE DOWN 1 AND OVER 2 FROM THE FIRST POINT OF (-2, 7), WE WILL LAND ON A POINT LOCATED AT (0, 6), WHICH WOULD BE THE "Y-INTERCEPT". WE WERE JUST ABLE TO CALCULATE THE SLOPE OF THE LINE AND THEN USE THE SLOPE TO FIND THE INTERCEPT. SO, THE "SLOPE-INTERCEPT" FORM OF THE EQUATION FOR THIS LINE IS:

y = -1/2x + 6

TO RE-WRITE THIS IN STANDARD FORM, WE JUST WANT TO MOVE THE X VARIABLE OVER TO THE LEFT WITH THE Y VARIABLE, SO:

y = -1/2x + 6

+1/2x + 1/2x

1/2x + y = 6 .... and that is your answer!

Answer:

$\sf f(-3) = 23$

<u>given:</u>

$\sf f(x) = 3x^2 -4$

to find the output, replace x with the given integer.

solve:

$\sf f(-3) = 3(-3)^2 -4$

$\sf f(-3) = 3(9) -4$

$\sf f(-3) = 27 -4$

$\sf f(-3) = 23$

Make, Dan, Ed, and summer played together on a baseball team. Mike’s batting average was 0.349, dan’s was 0.2, Ed’s was 0.35, an

lawyer [7]

the highest batting average is of Ed's and that is 0.350 .

<u>Step-by-step explanation:</u>

Here we have , Make, Dan, Ed, and summer played together on a baseball team. Mike’s batting average was 0.349, dan’s was 0.2, Ed’s was 0.35, and sy’swas 0.299. We need to find Who had the highest batting average . Let's find out :

According to question we have following parameters as :

$Mike = 0.349\\Dan's=0.200\\Ed's=0.350\\Sy'swas=0.299$

Arranging these data from decreasing to increasing order we get :

⇒ $0.200$

⇒ $(Dan's)0.200$

Therefore , the highest batting average is of Ed's and that is 0.350 .
