Question

Select the description that is true of the equation 3x + y = 7.

x-intercept equals -7

x-intercept equals 7

y-intercept equals 7 <--- is it this?

y-intercept equals -7

Answer 1

I believe it is that one

Answer 2

to find the y-intercept the equation can be written in slope-intercept form
y=mx+b where m is the slope and b being the y-intercept
solving 3x+y=7 for y will give you
y=-3x+7
The answer is the third option
y-intercept equals 7

hope this helped
