Step-by-step explanation:
Alternate way of doing this using the point-slope formula.
Since y = -3x + 1 is in y=mx + b format, the slope is -3.
m = -3
The slope of the line perpendicular to y = -3x + 1 must be -(1/-3), or 1/3, since m1 = -1/m2.
Point - slope formula:
y - y1 = m (x - x1).
y - 4 = (1/3) (x - 1)
y - 4 = (1/3)x - 1/3
y = (1/3)x - 1/3 + 4
y = (1/3)x - 1/3 + 12/3
y = (1/3)x + 11/3
Answer:
y = 3x + 7
Step-by-step explanation:
If the line is perpendicular to y = -1/3x + 3, then the slope will be the reciprocal of 3.
y = 3x + b
To find b, plug in the known point of (-1, 4)
4 = 3(-1) + b
Solve.
4 = -3 + b
7 = b
Your equation is: y = 3x + 7
