If we then plug in the slope<span> and y intercept into the slope-intercept formula of </span><span>y=mb+b</span><span> where </span><span>m=</span><span> the slope the </span><span>b=</span><span> the y intercept, then </span> <span>y=mx+b</span><span> becomes</span> <span>y=0x+<span>(−2)</span></span><span> which simplifies to </span><span>y=−<span>2 </span></span>
A slope of 0....this means that u have a horizontal line...which is represented by y = a number....with that number being the y coordinate of ur point (0,-2). Therefore, ur equation is : y = -2
learn this, it helps... HOY -- horizontal line, 0 slope, represented by y = a number VUX -- vertical line, undefined slope, represented by x = a number
