Answer:

x=7

Step-by-step explanation:

4x-7=21

  +7   +7    Add 7 to both sides to eliminate 7 and so you can have 4x=21 by its                     self

4x=28       Divide both sides by 4

x=7

Write the equation of the line that has a slope of m=3 and passes through (4 , 2)
mina [271]

Answer:

y=3x-10

Step-by-step explanation:

For this, you would use the point slope formula, which is (y-y1)=m(x-x1). x1 and y1 are the coordinates from the ordered pair.

(y-y1)=m(x-x1)

(y-2)=3(x-4)

y-2=3x-12

y=3x-10

To check, you can plug the coordinates into the equation.

y=3x-10

(2)=3(4)-10

2=12-10

2=2
