Answer:
y = x + 2
Step-by-step explanation:
To find the slope:
Find two spots where the line intersects and exact point. (-8,-4)(-4,-1)
Either count up & over or do y1-y2 / x1-x2 (-4+1)/(-8+4) -3/-4 3/4
The intercept is where it crosses the y-axis, in this case 2
Write the equation like this y = mx + b where m=slope & b=intercept
y = 3/4x + 2
Answer:
Obtuse
Step-by-step explanation:
The sum of squares of the short sides is 130, so is less than the square of the long side. The long side (12) is longer than it would need to be for a right triangle, so the largest angle is bigger than 90°.
The triangle is obtuse.
_____
A triangle solver app or calculator can confirm this. Note angle C is about 96°, an obtuse angle.
