First, we find the equation of the line...
(1,3),(-3,7)
slope = (7 - 3) / (-3 - 1) = 4/-4 = -1
y = mx + b
slope(m) = -1
use either of ur points.... (1,3)...x = 1 and y = 3
now sub into the formula and find b, the y int
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
so the equation for this line is : y = -1x + 4 which is usually written as :
y = -x + 4
Now...to find where the line crosses the x axis (or the x intercept)...we sub in 0 for y and solve for x
y = -x + 4
0 = -x + 4
x = 4... so ur x intercept (where the line crosses the x axis) is : (4,0)
Option C (Same as Option D)
<h2>
Explanation:</h2>
Option C and D are the same, so I'll assume you made a mistake when writing this question. However, let's figure out which of the following equations has a slope of -2 and passes through the point (2,3):
A. y = -2x + 6
B. y - 3 = -2(x + 2)
C. y = -2x + 7
<em />
<em>All these equations have a slope of -2.</em>
FROM OPTION A:

Since
then the line doesn't pass through the point (2, 3)
FROM OPTION B:

Since
then the line doesn't pass through the point (2, 3)
FROM OPTION C:

Since
then the line passes through the point (2, 3)
<em>Finally, the equation that has a slope of -2 and passes through the point (2,3) is Option C (Same as Option D)</em>
