PLEASE HELP I WILL GIVE BRAINLIEST!!!!!!
Natasha2012 [34]

Answer:

3rd answer EF =  2√13

Step-by-step explanation:

Make a right triangle and use Pythagorean theorem a²+b² = c²

Go from point  F 6 units down till point (1,-3) .From that point go 4 units left till you hit point E.

Triangle has legs a and b that are 6 and 4 units long so 6² + 4² = EF²

36 + 16 =  52

EF² = 52 find √52

EF = √52

There is no √52 as a whole number so rewrite 52 as a product of number who was a √ and the other who doesn't have a √

52 = 4 * 13

EF = √4 * √13 = 2√13

Please Help and write the equation down as well!!<br> I´ll mark whoever is right Brainiest!
wolverine [178]

Answer:

y=6x+4

Step-by-step explanation:

now the formula for slope-intercept is y=mx+b

Slope (aka m) is 6

[how I got the slope is every time it goes forward 1 it goes up 6  rise/run]

so y=6x+[y intercept]

the y intercept is 4 as seen in the chart so:

y=6x+4
