Answer:

y + 4 = 12 ( x - 1 )

Step-by-step explanation:

→ Work out the gradient

$\frac{-4-8}{-1-0} =12$

→ Substitute the numbers into the y - y₁ = m ( x - x₁ )

y + 4 = 12 ( x - 1 )

What's the answer to the question

Cloud [144]

First, find the slope of the line y-Ax=B
y=Ax+B, so the slope is A, which is a constant.
Because the new line is parallel to the given line, so the slope is also A.
Next, write the new line in point-slope form:
(y-3)=A(x-(-7)) =>y-3=A(x+7)
You can write it into slope-intercept form if needed: y-3=Ax+7A =>y=Ax+7A+3
or standard form: y-Ax-7A-3=0
