SOLUTION: Given the function 2x+y=7 find the following: a. X-intercept b. Y-intercept c. Slope I know I have to use y=mx+b, but I am so lost on how to solve this problem.

2x+y=7 SOLVE FOR Y
y = -2x + 7
y+=+highlight_green%28m%29x+%2B+highlight%28b%29
c. Slope = -2
********** y = -2x + 7 ********
a. X-intercept (when y = 0) x = 7/2
b. Y-intercept (when x = 0) Y= 7
