Can someone please explain to me a easier way of understanding this please

Step-by-step explanation:

u have solve it by finding slope(m)

and substitute is general eq of straight line

y = mx + c

step-by-step explanation:

no solution.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
