Answer:

c = 0

Explanation:

You want the value of c such that point (c, 4) is on the line with slope 1 through point (-7, -3).

Point-slope equation

The point-slope equation of a line with slope m through point (h, k) is ...

y -k = m(x -h)

The line with slope 1 through point (-7, -3) has equation ...

y +3 = 1(x +7)

y = x +4 . . . . . . . subtract 3 and simplify

(c, 4)

The value of x when y=4 can be found using this equation.

4 = x +4

0 = x . . . . . . . subtract 4

The value of c is 0.
