What is the y-intercept of the line that is
parallel to the line 2x + 10y = 7 and contains
the point (4, 9)?

Equation:  2x + 10y = 98

y-intercept:  (0, 9.8)

Step-by-step explanation:

The easiest possible way to solve thios problem follows:

Keep the form of the given line 2x + 10y = 7, replacing the '7' with the constant 'c:'

2x + 10y = c

Now take the coordinates of the given point (4, 9) and substitute them into the above equation, to find c:

2(4) + 10(9) = c

Then 8 + 90 = c, and c = 98

Then the desired equation is 2x + 10y = 98

To find the y-intercept, let x = 0 and solve for y.  We get

10y = 98, so that y = 9.8.  The y-intercept is thus (0, 9.8).

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
