What is the slope of the line that passes through (-2, 7) and (4, 9)? slope = -1/3 slope = 1/3 slope = 3 User: y is 5 when x is 2.5, and y varies directly with x. Find y when x is 10. 5 7.5 12.5 20
Weegy: we can model this in terms of a linear equation. y=mx+b Since the question states that y varies directly with x, we know that m (the slope of the line) is 1. [ so: y=x+b Now, to solve for be we can sub in the two known values for x and y to complete our equation. 6=2+b b=6-2 =4 So our final equation for the line is: y=x+4 when x=5 y=(5)+4 =9 ] (More)

The slope of the line that passes through (-2, 7) and (4, 9) is slope = 1/3. m = (9-7)/[4-(-2)]; m = 2/6 = 1/3

y is 5 when x is 2.5, and y varies directly with x. y is 20 when x is 10.

5/2.5 = y/10

2.5y = 50

y = 20
