Answer:

624

Step-by-step explanation:

the width is 104

if the length is doubled, that means the length is 208.

rectangles have 2 sets of equal sides

104 + 104 =208

208 + 208 = 416

416+208 = 624

Graph the line of the equation 8x/5 - 2y = -8 using its slope and y-intercept

satela [25.4K]

Answer:

$y=\frac{4}{5}x+4$

Step-by-step explanation:

You'll need to get this equation in slope-intercept form by solving for y. I do a little extra here to get it in the correct form, but I think it's pretty clear. Let me know if I need to clarify.

$\\\\\frac{8x}{5}-2y=-8\\\\-2y=-\frac{8x}{5}-8\\\\2y=\frac{8x}{5}+8\\\\y=\frac{4}{5}x+4$

Once it's in slope-intercept form, both the slope and the y-intercept are readily available so you can easily graph it. I graphed both of them in the attached image so you can see that they are the same line.
