Question 239031
The Slope-Intercept Form formula is: {{{y=mx+b}}}
.
All you need to do here is substitute the values.
.
y=5
x=-7
m=-2  (m=slope)
.
{{{5=-2(-7)+b}}}
.
Since 5 does not equal to 14, you must write "+b" in the equation.  If the equation had worked out without the "+b", then you could omit writing it.
