Question

Find the equation in point slope form of the line that is perpendicular to the line y=2x-3 and passes through the point (1,2)

Answer 1

First, do you know the formula to use

Answer 2

the point slope formula is y-y1=m(x-x1)

Answer 3

Point slope form:
\(y - y_1 = m(x - x_1)\)

perpendicular lines have an opposite (negative) reciprocal.
e.g.
\(2 \rightarrow -\frac{ 1 }{ 2 }\) \(\color{green}{\text{One-half is the perpendicular line's slope.}}\)

Find the new y-intercept by plugging in the x and y values from the coordinate \((1,2)\).
\(2 = m(1) + b\) and the \(m\) will be the perpendicular line's slope.

Answer 4

I do not know the formula @Abbs___

Answer 5

The formula was stated by both of us:

Once again it's:
\(y - y_1 = m(x - x_1)\)

Answer 6

the formula is y-y1=m(x-x1)

Answer 7

Oops sorry but anyways thanks both of you. @calculusxy and @Abbys___
