Answer:
y-1=2(x+4) or y=2x+9
Step-by-step explanation:
y - 3 = 2(x + 7)
y=mx+b
m=2
(x1,y1) -> (-4, 1)
(y−y1)=m(x−x1)
plug in
y-1=2(x+4)
y-1=2x+8
y=2x+9
test:
(1)=2(-4)+9
1=-8+9
1=1
I believe the correct number is 88.
3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = -8 (incorrect....no solution)
little tip ...
if it ends with a variable equaling a number, like x = 2 or y = 4, then there is 1 solution.
if it ends with something unequal with no variable, like 0 = -4 or 5 = 7, then there is no solution.
if it ends with something equaling with no variable, like 2 = 2 or 5 = 5, then there is infinite solutions.
<span>5x^2 - 7x + 2
5x^2 - 2x - 5x + 2
x(5x - 2) - (5x - 2)
(5x - 2)(x - 1)
The answer is: (5x - 2)(x - 1).</span>
