Y = mx + c

7= (-5)(-2)+ c

7= 10 +c

7-10=c

-3=c

Equation of the line: y = -5x-3

Sub in (a, 2)

2= - 5(a)-3

2+3= -5a

5= - 5a

1= - a

A = -1

4y -7 = 5 -2y +2y +2y add 2y to each side 6y -7 = 5 +7 +7 add 7 to each side y =
Simora [160]
4y - 7 = 5 - 2y

Add 2y to both sides.

6y - 7 = 5

Add 7 to both sides.

6y = 12

Divide both sides by 6

y = 2

What is the slope of the line that is perpendicular to the line whose equation is 2x + y = 4.<br>​
dusya [7]

Answer:

Step-by-step explanation:

Given equation is 2x+y=4 .so slope(m1) = - coefficient of x / coefficient of y= -2/1=-2

  • we have slope of the line perpendicular to the other line is m1*m2=-1\
  • then slope of the line perpendicular to the line 2x+y=4 is -2*m2=-1\
  • then -2/-1=m2 therefore m2 =2 .

C (d-b)/(c-a)

D (b-d)/(a-c)

Step-by-step explanation:

Identifying (x₁,y₁) and (x₂,y₂). We will use the formula to calculate the slope of the line passing through the points

slope =(y₂-y₁)/(x₂-x₁)
