Answer: y =
Step-by-step explanation:
We could find two points on graph to find the slope of the graph since we already know its y-intercept.The y-intercept is when x is 0.
We could find the points (0,-3) and another points ( 3,-2) to solve for the slope we will find the difference in y and divide it by the difference in the x values.
(0,-3)
(3,-2)
y -3 - (-2) = -1
x 0 - 3 = -3
-1/-3 = 1/3
so now we know the slope is 1 thirds or 1 over 3 and the y intercept is -3
so the equation will be y = 1/3x - 3
Answer:
i think it's
A)8.3
Step-by-step explanation:
You add the 4 and the 8 thats12. and than u go 100÷12=8.3
1. -7 + 9= -9 + 7 is false
2. Is 4x - 3 = 19 is open, because this could be a valid equation.
3. 16 = 4x - 4
So, 16+4=4x; 4x=20; x=20/4; x=5..... option C is the correct one.
4. length of the classroom is 2.4 times its width.
given length = 42 in, and since length = 2.4 times width, width = 42/2.4,
hence option A) 17.5 in is correct
5. x - 3 = 10
x = 10+3 =13
Option B is the right one.
Answer: 5...
Step-by-step explanation:
Answer:
<em>C. y = 3x + 13.</em>
Step-by-step explanation:
The point slope form of a line is
y - y1 = m(x - x1) where m = the slope, and (x1, y1) is a point on the line.
So, substituting:
y - 1 = 3(x - -4)
y - 1 = 3(x + 4)
y = 3x + 12 + 1
y = 3x + 13.
