HELP IM LITERALLY SOBBING

y=1/4x+2.75

Step-by-step explanation:

two coordinates are: (5,4) and (-3,2)

the linear function is y=mx+b

m=slope

b=y-intercept

first, find the slope

the formula to find the slope is y2-y1/x2-x1

2-4/-3-5=

-2/-8=

1/4

Now you know 1/4 is the slope.  Plug that into the function

y=1/4x+b

Now find the y-intercept

to do that, take one of your coordinates and plug the x and y values into the function.

I will use (-3,2)

2=1/4(-3)+b

2=-3/4+b

11/4=b

(or 2.75 decimal form)

Plug the y-intercept into the function and you're done

y=1/4x+2.75

x = sqrt(45)

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

2^2 + x^2 = 7^2

4+x^2 = 49

Subtract 4 from each side

4-4+x^2 = 49-x

x^2 = 45

Take the square root of each side

sqrt(x^2) = sqrt(45)

x = sqrt(45)
