Answer:
Below in bold.
Step-by-step explanation:
Area = altitude * base
3. 6.2 * 6
= 37.2 cm^2.
4. 0.12 * 0.24
= 0.0288 m^2.
5. 32 * 0.4
= 12.8 m^2.
Answer:
y = 3x + 5
Step-by-step explanation:
First start at your y intercept (5) and use the rise to run ratio (rise 3, run 1) and there is a point on every single one.
1/3 wouldn't work because you rise 1 and go right 3 and that does not match any of the points
Using the two points first gives us a slope of 3
(1, 8) (2, 11)
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 8)/(2 - 1)
m = 3/1
m = 3
We also know that 8 cannot be the intercept being as it is the point at x = 1. Therefore, we know that y = 3x + 5 must be the only possible answer.
Rearrange it to its 3y= 7x+15. Then divide both sides by 3 to get y=7/3x+5
This question can be answered by graphing, but first you need to write an equation using slope- intercept form
y=mx+b , where m is the slope and b is the y intercept
