Answer:

Using substitution method

First make y in equation 1 the subject of formula

Y=4x-2

Sub in equation 2

2(4x-2)-8x=4

8x-4-8=4

8x=4+12

8x=16

X=2

Sub in any of equation to get y

Step-by-step explanation:

Y =4(2)-2=6

Standard form of (-2,0)

Flauer [41]

The formula you can use is

y - y1 = m(x - x1)

plug the y value you are given into y1 and the x value you are given into x1. m is for your slope value. after you plug in the known values, solve. your final answer should be in standard form which is

Ax + By = C

your answer should not contain any fractions and your Ax value cannot be a negative value, By and C can be negative though.

hope this helps :)
