Answer:
y= -1/2x+5
Step-by-step explanation:
The formula you need to use is (y-y1)=m(x-x1)
x1=the x point provided
y1=the y point provided
m=the slope
Simply plug the numbers into the equation to start.
(y-3)= -1/2(x-4) Now we need to distribute the slope to both terms inside the parenthesis.
-1/2(x)= -1/2x
-1/2(-4)= 2 Now you put them back into the equation.
(y-3)= -1/2x+2
At this point you can get rid to the parenthesis around y-3 because it is basically saying to take it times 1.
y-3= -1/2x+2 Finally to get y alone you would add 3 to both sides.
+3 +3
y= -1/2x+5

Answer:</h3>
y = 4x + 4
<h3>
Step-by-step explanation:</h3>
The equation of a line is most commonly given in the slope-intercept form.
Slope-Intercept Form
Slope-intercept form is given by the formula y=mx+b, where m is the slope and b is the y-intercept. This form is most commonly used because it is easy to draw a graph from and it is very concise. We already know one of the constants, m = 4. So, to find the equation we need to solve for b.
Solving For b
To solve for b, we need to plug in all of the information that we are given into the formula. We are given 3 pieces of info for this point: y = -8, x = -3, m = 4.
Then, multiply.
Finally, add 12 to both sides.
Now that we know the value of b, we can go back to the formula and plug in both constants, y = 4x + 4.
Answer:
x=14
y=10
Step-by-step explanation:
The median divide the data‘s set into two parts with the same frequency = 50%
then we must have 2+5+x+12+17 = 50 ⇔ 36+x=50 then x =50-36=14
also 20+y+9+7+4=50 ⇔ y=10
The top corner is 180-78=102°
Sum of the corners should be 180°, so
39+102+5z+4=180 => 5z = 180-145 => z=35/5=7°
my previous answer of 29 was indeed wrong!!!
sorry for that!!
