If you know the ratio between a and b, assign the value of a to x and b to y.
You set the slope as b/a. The equation of the line would be y = (b/a)(x)
Any point on the line (besides the origin) would be an equivalent ratio (a:b would be x:y)
Answer:
<h3>x<2</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
x-6+6<-4+6 (First, add 6 from both sides.)
-4+6 (Solve.)
-4+6=2
x<2
Therefore, the correct answer is x<2.
Answer:
199.5 ft^3
Step-by-step explanation:
to find your answer you simply multiply all the measurements together
19 * 1.5 * 7 is your equation
19 * 1.5 * 7 = 199.5
it is 199.5 ft^3
Answer:
$204.4
Step-by-step explanation:
The four chairs bought in June cost $35 each, all together $140. Then they bought 2 more chairs on sale for 8% off of $35 each or 92% of $35 which is $32.2 each, all together $64.4. Both buy's together would then equal $204.4
Answer:
y = -6x - 5
Step-by-step explanation:
To find the equation using the point-slope equation, we need the slope and the y-intercept of the line
<u>Finding the slope of the line:</u>
We will calculate the slope between these 2 points: (-1 , 1) and (0 , -5)
Slope = Rise / Run
Rise of the line = y1 - y2
Rise = 1 - (-5)
Rise = 1 + 5
Rise = 6
Run of the line = x1 - x2
Run = -1 - 0
Run = -1
Slope of the line:
<em>Slope = Rise / Run</em>
<em>Slope = 6 / -1</em>
<u>Slope = -6 </u>
<u></u>
<u>Finding the y-intercept:</u>
y-intercept of a line is the y-ordinate of the point where the line intersect the y-axis
From the graph, we can see that the line intersects the y-axis at (0 , -5)
y-coordinate of the point = -5
<u>y-intercept = -5</u>
<u></u>
<u>Equation of the line:</u>
This is the general formula of the slope-intercept:
y = mx + b (where m is the slope of the line and b is the y-intercept )
Replacing the variables
y = (-6)x + (-5)
y = -6x - 5
