Finding Slope of a Line
What is the Point-Slope form of a linear equation?
What is the slope of a line perpendicular to y = 2/3x + 4
The slope is the negative reciprocal -3/2
m = y2 - y1 / x2 - x1
x - 2y = 2
Write the equation of a line with a y intercept of -2 and perpendicular to y = 3/4x + 5
y - 4 = 2/3 ( x+ 3 )
Write an equation in point-slope form for a line with the following two points intercept. (4, -7) (9, -10)
y + 10 = -3/5 (x - 9) or y + 7 = -3/5 ( x - 4)
