How do i find the slope and y intercept ?
2 answers:
Here are the instructions. Then we'll do your specific problem.
Step 1: Solve the equation for y, and write it in the form y = mx + b.
Step 2: The slope is m, and the y-intercept is b.
Now let's start.
-2x - 5y = -20
To solve for y, we first add 2x to both sides.
-5y = 2x - 20
Now we divide both sides by -5.
Now we compare what we got with the form, y = mx + b.
We see that m = -2/5, and b = 4. m is the slope, and b is the y-intercept.
slope: -2/5
y-intercept: 4

Answer:
(B) Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4 (one-half (8) (6.9))
Step-by-step explanation:
Base of the Pyramid = 8 Inches
Height of the Triangular Face = 6.9 Inches
In any solid shape, the Lateral surface area is the sum of all sides except its top and bottom bases.
Since the four triangles are congruent:
Lateral Surface Area = 4 X Area of One Triangle
Area of a Triangle =
Area of one Triangular Face
Therefore:
Lateral Surface Area
Therefore, Talia is correct.
