Answer:
y = -2x + 3
Step-by-step explanation:
y2 - y1/ x2 - x1
7 - (-5) / -2 - 4
-2
The slope is -2.
To find the y-intercept, you need to plug the coordinates into the equation.
y = -2x + b
7 = -2(-2) + b
7 = 4 + b
3 = b
y = -2x + 3
2 + 4(3+2x) = 3x + 8
2 + 12 + 8x = 3x + 8
14 - 8 = 3x - 8x
6 = -5x
x = -6/5
Answer: she had 98 flowers
Step-by-step explanation: (4+3)x(7x2)
Answer(s):
If you are asking for the equation, it's 9(x+4)=2
However, if you're asking for the value of x as well, it's -34/9
Step by Step:
1) First we must find the equation. In your question, the unknown number is x. Therefore we can know that "the sum of a number and 4" is (x+4). Since we are multiplying this sum by 9, we can put the 9 in front of this expression to multiply it--getting 9(x+4). And since we know it "is 2" we can say that 9(x+4)=2.
2) Now, we have to solve the equation, 9(x+4) = 2
3) We can start by distributing, 9x+36 = 2
4) Now let's move 36 to the right by subtracting from both sides, 9x = -34
5) To isolate x, let's divide both sides by 9, x = -34/9
6) Our fraction answer can't be simplified, so we get x = -34/9
Answer:
Step-by-step explanation:
Remark
You can use the two points marked to find the slope. One of them is the y intercept which you need to get the equation.
(0,4) is one of the points. This is the y intercept.
(8,0) is the other point you can use
Slope
m = (y2 - y1)/(x2 - x1)
Givens
y2 = 4
y1 = 0
x2 = 0
x1 = 8
Solution
m = (4 - 0) / (0 - 8)
m = 4/-8
m = - 1/2
y_intercept = 4
Equation
y = -1/2 x + 4
