Answer 1

Welcome to QC

The slope-intercept equation of a line is \(y=mx+b\)
m = slope
b = y-intercept


The question gave us the y-intercept (0,-3), so we can substitute that for b
\(y=mx-3\)

They also gave us a point (3,0) [Remember that points are written as (x,y) which is also included in the equation] Substitute this into the equation we have
\(0=m(3)-3\) => \(0=3m-3\)

Now you need to simplify by isolating the m
