1. What will the first step look like for the substitution problem: y = 2x 7+ y = 9 Ox+ 2x = 9 y = 27. + 9 O y + 2x + x + y = 9 2y+y = 9​

2? if not the correct answer you might need to provide more information

step-by-step explanation:

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

answer is because 4×10=40

and 98×4= is 392

40,392
