What is the solution to this system of linear equations? 7x – 2y = –6 8x y = 3 (–6, 3) (0, 3) (1, –5) (15, –1)

Step-by-step explanation:

we have

----> equation A

----> equation B

Multiply the equation B by 2 both sides

------> equation C

Adds equation A and equation C

Find the value of y

the solution is the point

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
