Answer:
don't cry because it is over smile because it happened
Step-by-step explanation:
Substitute y in 8x - 3y = -22.
8x - 3(5x + 19) = -22
Simplify.
8x - 15x - 57 = -22
Simplify.
-7x - 57 = -22
Add 57 to both sides.
-7x = 35
Divide both sides by -7.
x = -5
Substitute x in y = 5x + 19.
y = 5(-5) + 19
y = -25 + 19
y = -6
The solution is (-5, -6).
Given transformation is f(x+5) which is similar to f(x+h).
f(x+h) shifts the graph "h" units to the left side.
so that means f(x+5) will shift the graph "5" units to the left side.
Left or right movement is done using x-coordinate only so -3 will change in (-3,7)
-3+5=2
so the new coordinate of the point will be (2,7)
Hence final answer is (2,7).

Answer:
3x - y = -7
Step-by-step explanation:
y = mx + b
m = deltay/deltax
m = (10 - 1)/[( 1 - (-2)]
m = 9/3 = 3
y = 3x + b
From (-2 | 1) we see that when x = -2, y = 1
Placing into the equation, in order to find b (y-intercept)
y = 3x + b
1 = 3(-2) + b
b = 7
y = 3x + 7 or 3x - y = -7
