Answer:
D
Step-by-step explanation:
To find the intercepts, that is where the line crosses the x and y axes
• Let x = 0, in the equation for y-intercept
• Let y = 0, in the equation for x- intercept
x = 0 : - 3y = - 9 ⇒ y = 3 ⇒ (0, 3) ← y- intercept
y = 0 : x = - 9 ⇒ (- 9, 0 )← x- intercept
Probably you are supposed to compute
Factorize the numerator and denominator, then simplify:
The value of x is -2 and the value of y is -1.
Step-by-step explanation:
Step 1; The given equations are taken as
-3y -9x =21 or -9x -3y = 21, take this as equation 1
-18x +4y =32, take this as equation 2
Step 2; We multiply equation 1 with 2 and equation 2 with 1 so we can cancel out the variable x in both equations. By doing this we get
-18x -6y =42, take this as equation 3
-18x +4y =32, this is the same as equation 2
If we subtract 3 with 2, we cancel out the x variable and can calculate the value of y.
10y = -10 , y = -10/10 = -1
Step 3; Substituting this value of y in any of the previous equations we will get x's value. Here this value of y is substituted in equation 2.
-18x +4(-1) =32, -18x -4 = 32 , -18x = 36, x=-2.
So we have x = -2 and y = -1.
