I need help solving systems of linear equations by substitution.
e-lub [12.9K]

Answer:

x = 2 and y = 1

Step-by-step explanation:

4x = 5+3

4x = 8

x = 8/4

x= 2

so substitute the value of x in the second problem

-8(2) + 6y = -10

-16 + 6y = -10

6y= -10 + 16

6y= 6

y= 6/6

y = 1

A line has a slope of -2/3 and passes through the point (-3, 8). What is the equation of the line?
dexar [7]

Answer:

y= -2/3x+6

Step-by-step explanation:

Using slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = -2/3x +b

Substitute the point into the equation

8 = -2/3(-3) +b

8 = 2+b

8-2 =b

6=b

y= -2/3x+6
