find the value of y so that the line passing through the two points has the given slope (0,y,) (2,5),m=2

Question

my questions are like find the slopes and values

Answer 1

The slope is given, m = 2, so need to find y 

 

x1 = 0  y1 = y   x2 = 2   y2 = 5

 

slope = m = (y2 - y1)/(x2 - x1) = 2          

 

  since y = y1, solve for y1:

 

y2 - y1 = 2*(x2 - x1)

 

y2 - 2*(x2 - x1) = y1

 

or y = y1 = y2 - 2*(x2 - x1) =  5 - 2*(2 - 0)  = 5 - 4 = 1

 

therefore, y = 1
