Answer:

y = 2x - 8

Step-by-step explanation:

Since you have the slope of the line and point that the line passes through, you can use "point-slope form", hence the name.

Point-slope form is: y-y_1=m(x-x_1)

Substitute the slope (2) into m, and substitute the x-value of the point into x_1 and the the y-value of the point into y_1.

  • y-(-4)=2(x-(2))

Simplify this equation.

  • y+4=2(x-2)

Distribute 2 inside the parentheses.

  • y+4=2x-4

Subtract 4 from both sides.

  • y=2x-8 is the final answer.

Kryger [21]

Answer: y= x-2

Step-by-step explanation:

Perpendicularity entails the slope of line a is -1 divided by the slope of line b

m1= (-1/m2)

From y=Mx +c

We compare with x-4y=7

y=(1/4)x-7/4

Meaning m2= 1/4

m1= -1/(1/4)= -1*4= -4

((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1

x1= 2, y1= -4

((y-(-4))/(x-2))= -4

((y+4)/(x-2))= -4

Cross multiply

y+4= -4(x-2)

y= x-2
