Question

Write the equation in slope-intercept and standard form for the line that goes through the points (1,3) and (2,5).








What is the slope of the equation that is perpendicular to the line above?

Answer 1

do you know how to find the slope of this line?

Answer 2

Nope

Answer 3

m=2. y=2x+1, then to find perpendicular we need the slopes to multiply to -1 (I used -1/2) so the equation of the perp. line would be y=-(1/2)x+1

Answer 4

to find the slope (how I got m) is delta y over delta x. (5-3) / (2-1) = 2/1 = 2
