Question 82859
Write the equation of the line with x-intercept (16, 0) and y-intercept (0, 4).
In order to write the equation of a line, you need a point and a slope.
You don't have a slope, but you can find it using the point slope formula: {{{highlight(m=(y[2]-y[1])/(x[2]-x[1]))}}}, where m=slope, (x1,y1) and (x2,y2) are your given points.
(x1,y1)=(16,0) and (x2,y2)=(0,4)
{{{m=(4-0)/(0-16)}}}
{{{m=4/-16}}}
{{{m=-1/4}}}
You can use the slope intercept form of the line to make an equation when you have a slope and the y-intercept.  {{{highlight(y=mx+b)}}}, m=slope and (0,b)=y-intercept
m=-1/4 and (0,b)=(0,4)
{{{y=(-1/4)x+4}}}
Happy Calculating!!!
