Question

Find the equation of the straight line joining the points (-5,2) and (3,-4)​

Answer 1

Answer:

y= -0.75x+5.75

Step-by-step explanation:

so, if y=mx+c

the gradient is m, which is equal to (y1-y2)/(x1-x2), (2--4)/(-5-3) = 6/-8=-0.75

so y= -0.75x+c

substitute y and x values

2(y)= -0.75(m)*-5(x)+c

2=-0.75*5+c

2= -3.75+c

5.75=c

so in the end, y= -0.75x+5.75

Answer 2

Answer:

3x+4y+7=0.... equations (1)

which is required equations
