If x is negative, then 10-x must be positive.
for example: let's say x=-1. then 10-(-1)=11
Yo sup??
4x+5y=-9
y=(-4x)/5-9/5
we see that this is of the form y=mx+c
where m is the slope
therefore the slope of the line is -4/5
To find y intercept, put x=0
y=-4*0/5-9/5
y=-9/5
Therefore y intercept is -9/5
Hope this helps.
Vertex Q is 6 units from vertex R
Vertex R is 7 units from vertex T
Vertex T is 3 units from vertex S
Combine like terms, 1+6 is 7 and 2t+4t is 6t. so 6t+7=55. get the t by itself by subtracting 7 from both sides. 6t=48, divide by 6. t=8
First you have to isolate one of the equations for y=mx+b.
Then substitute the equation is made into the first equation
