Answer:
4y+x = -4
Step-by-step explanation:
For the line x = -5, this is an x intercept written as (-5, 0)
Next is to find the equation of a line passing through (-5,0) and (3, -2)
Slope m = -2-0/3-(-5)
m = -2/8
m = -1/4
Get the y intercept
Substitute m =-1/4 and (-5,0) into the expression y - mx+c
0 = -1/4(-5) + c
0 = 5/4 + c
c = -5/4
Get the required equation;
y = -1/4 x - 5/4
4y = -x - 4
4y+x = -4
This gives the required equation
Answer:
It's a simultaneous equation because it as two solution
Step-by-step explanation:
K= -3
3y = x+6 can be rewritten as y = 1/3x + 2
a perpendicular slope is the opposite reciprocal of the original slope
so instead of 1/3 it would be -3
therefore. k must equal -3 to be perpendicular to 3y = x+6
The probability that it doesn't land on 4 would be 3/8. This is because theres a 5/8 chance it lands on 4 so just do the opposite which would be 3/8.
