Find the equation of a line that passes through the point ( 5, − 7) and is perpendicular to the line y = − 1 3 x − 9. First, find the slope of the given line. This line is in

You can find the slope of a line perpendicular to this line by using the points and going through (y2− y1) (x2 − x1) ( y 2 - y 1) ( x 2 - x 1), or you can just nab it right out of the slope-intercept form! Yes, the slope of this line is 3 4 3 4. The 2 2 is

The dot-product of the vectors A = (a1, a2, a3) and B = (b1, b2, b3) is equal to the sum of the products of the corresponding components: A∙B = a1_b2 + a2_b2 + a3_b3. If two

Convert the equation to slope intercept form to get y = –1/3 x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
