What is the equation of the line that goes through the points (-5,-1) and (5,5)?
Margaret [11]

Answer:

y = 3/5 x + 2.

Step-by-step explanation:

Use the point-slope equation of a straight line:

y - y1 = m (x - x1) where m = the slope amd (x1, y1) is a point on the line.

Here:

m = (5- (-1)) / (5 - (-5))

= 6/10

= 3/5.

Substituting for m and  (5, 5):

y - 5 = 3/5(x - 5)

y - 5 = 3/5x - 3

y = 3/5 x + 2.

LekaFEV [45]

Answer:

2X^2+5/2X-3/2=0

Step-by-step explanation:

To identify the equation use the following method

(X-a)(X-b)=0

Put values

a=-4

b=3/2

(X+4)(X-3/2)=0

X^2+4X-3/2X-3/2=0

X^2+(8X-3X)/2-3/2=0

X^2+5/2X-3/2=0
