Answer:
a)
b)
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.
Point slope:
a) in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is
.
We will substitute and
.
This simplifies to:
b) The equation y=3x+4 follows y=mx+b. For the perpendicular line, . We will need to change it into its negative reciprocal which is
.
We will substitute and
.
