Answer:
x=-20/18
Step-by-step explanation:
-1/2x=(5x+10)/8= -18x=20
therefore x=-20/18 =-1.111111
Gradient is
if you have
ax+by=c
gradient (aka slope)=a/b
we have
-4x+2y=16
a=-4
b=2
gradient=-4/2=-2
y intercept is when the line crosses the y axis, also that is when x=0 so set x=0 and solve for y
-4(0)+2y=16
0+2y=16
2y=16
divide 2
x=8
y intercept=8
gradient=-2
y intercept=8 (y=8 aka point (0,8))
Answer: 
Step-by-step explanation:
To find the y-intercept, substitute in 
for 
and solve for 
.
Use the slope-intercept form 
to find the slope 
.
It’s a because it is pi is the diameter and the circumference it’s divided by 2 million percent
expand, thus you can sum like-terms if any.
