Answer:

y = 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (1, 8 ) into the partial equation

8 = 3 + c ⇒ c = 8 - 3 = 5

y = 3x + 5 ← equation of line

Need help ASAP !!! And show work please

Answer:

$\sqrt{40}$ or 6.32

Step-by-step explanation:

We can find the distance between two points by using this formula

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

where the x and y values are derived from the given points

The points given are ( -2 , 5 ) and ( 4 , 3 )

So we plug in the x and y values of those coordinates into the distance formula

$\sqrt{(4-(-2)^2+(3-5)^2} \\4-(-2)=6\\3-5=-2\\d=\sqrt{6^2+-2^2} \\6^2=36\\-2^2=4\\36+4=40\\d=\sqrt{40}$

or 6.32
