You have to use point slope form
point slope form: y - y1 = m(x - x1)
x1 and y1 are the x and y values of the given point
m is the slope
so, just plug in the numbers:
y-3 = -2(x + 8)
now solve to put into slope intercept form (y = mx + b)
y-3 = -2x - 16
ANSWER: y = -2x -13
Answer:is it 45+(35-13)
Step-by-step explanation:

1. Given any triangle ABC with sides BC=a, AC=b and AB=c, the following are true :
i) the larger the angle, the larger the side in front of it, and the other way around as well. (Sine Law) Let a=20 in, then the largest angle is angle A.
ii) Given the measures of the sides of a triangle. Then the cosines of any of the angles can be found by the following formula:
2.
3. m(A) = Arccos(-0.641)≈130°,
4. Remark: We calculate Arccos with a scientific calculator or computer software unless it is one of the well known values, ex Arccos(0.5)=60°, Arccos(-0.5)=120° etc
