Question

Write in point-slope form an equation of the line through each pair of points

Answer 1

Answer:

y=-x-7

Step-by-step explanation:

Point slope form --> y=mx+b where m=slope & b= x intercept:

Slope = delta x / delta y;

delta x = -10 - (-2) = -8;

delta y = 3 - (-5) = 8; therefore Slope = -1

b --> y = mx + b plug one set of coordinates into equation & solve for b:

3 = (-1)(-10) + b --> b = 3 - 10 = -7

Taking all rhat inro account you get answerg

y = (-1)x - 7

Answer 2

Answer:

Answer:

Solution given:

$(x_1,y_1)=(-10,3)$

$(x_2,y_2)=(-2,-5)$

now

slope:$\frac{y_2-y_1}{x_2-x_1}=\frac{-5-3}{-2+10}=\frac{-8}{8}$

Slope: -1
