A line passes through the points (1,1/2) and (3,2) which is the equation of the line
otez555 [7]

Answer:

The equation of the line is y = 3/4x - 1/4

Step-by-step explanation:

To find the equation of this line, start by using the two points with the slope formula to find the slope.

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

m = (2 - 1/2)/(3 - 1)

m = (3/2)/2

m = 3/4

Now that we have the slope, we can use that and either point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - 2 = 3/4(x - 3)

y - 2 = 3/4x - 9/4

y = 3/4x - 1/4

Find x when y=3 in the literal equation 3x+6y=24
pshichka [43]
When you plug in 3 in for y the equation is 3x + 6(3) = 24

3x + 18 = 24

subtract 18 from both sides

3x = 6

Isolate the x by dividing both side by 3

x = 2
