Mrs. Maldonado has 100 more pencils than Mrs. Rodriguez. If Mrs. Maldonado has
325 pencils, how many pencils do both teachers have?

550

Step-by-step explanation:

Mrs. Rodriguez: 325-100 =  She has 225 pencils

225+325= 550

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
