ABOUT THIS FORMULA:
X2 - X1
FOR PROBLEM: (2, 1) & (0, -5)
- Y2 is -5
- Y1 is 1
- X2 is 0
- X1 is 2
ABOUT POINT SLOPE FORM:
- y - Y1 = m(x - X1)
- Y1 & X1 is a point
- m represents the slope
- This form allows you to identify the slope & the point on the line
ABOUT SLOPE INTERCEPT FORM:
- y = mx + b
- m represents the slope
- b represents the y - intercept AKA the starting point
<u>Y2 - Y1</u>
X2 - X1
<u>-5 - 1</u>
0 - 2
<u>-6</u>
-2
SIMPLIFIED: -3 because both -6 & -2 can be divided by 2.
y - Y1 = m(x - X1)
y - -1 = -3(x - 2)
y + 1 = -3x + 6
- 1 - 1
y = -3x - 5 --- SLOPE INTERCEPT FORM
I do not see y = -3x - 5 as one of your answer choices.... So, I am sorry if I am incorrect...
Answer:
c= 261
Step-by-step explanation:
-c = -11 - 250
-c = -261 change the signs on both sides of the equation c = 261

sorry i dont get it
Step-by-step explanation:
Answer: x is 9° , y is 21°. The measure of angle ABE is 48°.
Step-by-step explanation:
First we will solve for x.
The variable x appears in the angle 8x + 18 and that angle is a right angle.
Right angles have the measure of 90 degrees so we will set the angle equal 90 and solve for x.
8x + 18 = 90 Subtract 18 from both sides
- 18 -18
8x = 72 divide both sides by 8
x = 9
y is also on the right side and the combination of both angles has to also equal 90 degrees because they form a right angle.
Since we already know x is 9 we will input it into the left side for x and solve for y.
y + 3(9) + 2y = 90
3y + 27= 90
-27 -27
3y = 63
y = 21
Now we need to find the measure of angle ABE.
ABE is represented by y + 3x so since we know the value of y and x we will input it into the expression and solve for the angle.
21 + 3(9) = m∠ABE
21 + 27= m∠ABE
48 = m∠ABE
This means the measure of angle ABE is 48°
