the line passing through the points (1,2) and (x, 5) is perpendicular to a line that has a slope of 1/3. what is the value of x

x= 0

Step-by-step explanation:

Let's form an equation using the slope of the line.

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate

Let the gradient of line be m.

The product of the gradients of 2 perpendicular lines is -1.

m(⅓)= -1

m= -1 ×3

m= -3

x= -1 +1

x= 0
