The equation Y-1=-7(x-3) is written in point-slope form. What is the y-intercept of the line? -4
-2
20
22

9514 1404 393

  22

Step-by-step explanation:

Substitute 0 for x and solve for y.

  y -1 = -7(0 -3)

  y = 21 +1 . . . . . . add 1

  y = 22 . . . . . . . . the y-intercept

how is that middle school

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
