Answer:
(20,0)
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1)
(-5,-5).....x1 = -5 and y1 = -5
(10,-2)...x2 = 10 and y2 = -2
slope = (-2 - (-5) / (10- (-5) = (-2 + 5) / (10 + 5) = 3/15 = 1/5
y = mx + b
slope(m) = 1/5
use either point, I will use (10,-2)...x = 10 and y = -2
now we sub
-2 = 1/5(10) + b
-2 = 2 + b
-2 - 2 = b
-4 = b
so the equation for this line is : y = 1/5x - 4
to find the x intercept, sub in 0 for y and solve for x
y = 1/5x - 4
0 = 1/5x - 4
-1/5x = -4
x = -4 * -5
x = 20.......so ur x intercept is (20,0) <====
Answer:
Step-by-step explanation: 
= (4,0)
7(5x+3y=27)
-5(7x+9y=51)
———————
35x+21y=189
-35x-45y=-255
————————
-24y=-66
Y=-66/-24
Y=2.75
——————-
Now replace Y with one of the equations to find x
—————
5x+3(2.75)=27
5x+8.25=27
5x=27-8.25
X=18.75/5
X=3.75
——————
Final answer =
X=3.75
Y=2.75
