First of all, to find the slope, you need to subtract the y's in the numerator over the x's in the denominator. Then you use Y-Y₁=slope(X-X₁) using either of the two points. If you want to simplify it further into slope-intercept form, you need to distribute on the right side of the equation.
If is an acute triangle, all the angles should be acute angles.
180-38=142°
142-69=73°
So your answer is 69°, lovely~
The slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
We know:
Slope (m) is -4
y-intercept (b) is -1
All you need to do is plug these numbers into the slope intercept formula given above!
y = -4x - 1
Hope this helped!

Answer:
4/40
Step-by-step explanation:
you can reduce this to 1/10
multiplying 4 by both 1 and 10 will give you the fraction 4/40 both can be divided by 4 and that's how it can reduce to the 1st fraction (1/10)
Answer:
x = 8; y = 29
Step-by-step explanation:
In a parallelogram, opposite angles are congruent.
8x = 7x + 8
x = 8
4y = y + 87
3y = 87
y = 29
