Answer:
15.59.
Step-by-step explanation:
The altitude of equilateral triangle bisects the base
So 1/2 base = 3.
Altitude of the triangle is found from Pythagoras theorem:
= sqrt(6^2 - 3^2)
= sqrt27
Area = 1/2 base * altitude
= 3 * sqrt27
= 15.59
If this is for slope-intercept, the equation is: y = 3x + 1
To find the slope, you would find the rise over run ( 
). So, you would start where the graph intersect at the y-axis, which is 1. You would go up 3 times, and right 1 time. So, 
, or 3, would be your slope. To find the y-intercept, you would need to find where the graph intersects at the y-axis, which is 1, so it would be your y-intercept. Plug them into the y = mx + b formula and the answer is <em>y = 3x + 1</em>.

Slope is the change in Y over the change in. X
Using two of the given points:
Slope = 70-45 / 25-10
Slope= 25/ 15
Slope = 5/3
