I think the first one might be 18 second might be 10
Y intercept when x =0
<span> y=-x+3
y = -0 +3
y = 3
</span><span> the slope is -1 </span>

It is (C) because the line is ZERO meaning the line is vertical and since it goes through 5, it is y=5 cuz u always have the formula for slope; y=mx+b and since there is o x intercept you just stick with the y intercept which is 5 so long story short, it is y=5 (c)
