Ok so i did learn this and was really good at it but now that i have to do it i do i find the perimiter and dont call me dumb

Hi!

So what you want to do is to find the perimeter add the sides up 4 times or mutiply 3.5 and 4. It's the same thing

Perimeter: 3.5*4= 14

For area multiply 2 sides and only 2 sides which are the length and width

Area: 3.5 * 3.5 = 12.25

Hope this helps!!

for the perimeter you add 3 1/2 four times of multiply it by 4 and for the area you do 3 1/2 times 3 1/2

Slope-intercept form is y = mx+b
you can tell the slope because slope = rise/run or the change in y per change in x.
change in y = |0 + -4| = 4  = 1
change in x     |4 + -8|     4
slope = 1

since when x=0, y=4, then the y-intercept is 4

so the slope-intercept form is y = (1)x + 4 = x + 4
