Find the equation of the line parallel to 2y-3x= 4 and passing through the point (6,7)
frutty [35]

Answer:

We have equation of a line:

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

The equation of the line that is parallel to above line and passes through the point (6, 7) would have form y = ax + b, and

a = 3/2

6a + b = 7

=> b = 7 - 6a = 7 - 6 x 3/2 = 7 - 9 = -2

=> The equation of that line: y = (3/2)x - 2

Hope this helps!

:)

kozerog [31]
Hello! One number is negative and the other one is positive. In this case, we should find the difference they are from 0 and add the numbers up. -11 is 11 units away from 0. 17 is 17 units away from 0. 11 + 17 = 28. The difference in temperature is 28 degrees Celsius.
