Answer:
(x=0, y=11)
(x=2, y=9)
Step-by-step explanation:
first equation substitution for x first.
y=11-x
plug into 2nd equation
(x+2)^2+(11-x-7)^2=20
this should lead you into a quadratics equation.
you get x=0, x=2.
do the same for y value this time, subbing in the x value
(11-y+2)^2+(y-7)^2=20
this also leads into a quad equation
solve and you get y=11, and y=9
Answer:
The slope is 1/2 and the y intercept is 7/4
Step-by-step explanation:
2x-4y+7=0
To find the slope, we need to put the equation in slope intercept form
y = mx+b
So we need to solve for y
Subtract 2x from each side
2x-2x-4y+7=0-2x
-4y +7 = -2x
Subtract -7
-4y+7-7 = -2x-7
-4y = -2x-7
Divide by -4
-4y/-4 = -2x/-4 -7/-4
y = 1/2 x +7/4
The slope is 1/2 and the y intercept is 7/4
