Answer:

Step-by-step explanation:
1. The slope-intercept form of a linear equation is
, where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.
2. To find the slope, let's take the two points (0,0) and (-40,10). After that, let's plug in the values to their corresponding variable in the formula:
3. Since we now know our slope, the equation looks like this so far:
.
4. Because b is the y-intercept, b = 0 because the line intersects the y-axis at (0,0).
5. Now that we have the values of m and b, we plug in them to get the equation of: 
Answer:
5.1
Step-by-step explanation:
Add 4.3 to 0.8
Answer:
C
Step-by-step explanation:
The key word is x-axis, and since the bottom line is the x, just look for a reflection of it.
Simply 3^2 to 9
2×2+9−4+3×5
Simplify 2 x 2 to 4
4+9−4+3×5
Simplify 3 x 5 to 15
4+9−4+15
Simplify
= 24
Answer:
x = 29.15
Step-by-step explanation:
a^2 + b^2 = c^2
15^2 + 25^2 = 890
square root of 850 is 29.154759....
