Question

equation in slope-intercept form.

Answer 1

Do you know the point-slope formula?

Answer 2

The slope(m) formula is this :
Y2-Y1/X2-X1=m
Y1=-4
X1=-4
X2=1
Y2=4
Got it ?

Answer 3

yes
y2-y1/x2-x1 never mind I got it

Answer 4

Then we have :
Y2-y=m(X2-x)
So :
Y2=4
X2=1

Answer 5

Just have :
m=-4-4/-1-1=-8/-2=4
So have :
4-y=4(1-x)
4-y=4-4x
And get it in standard form .
Got it ?

Answer 6

And in second :
x=180-(36+63)
And :
x+z=180
If you find x can answer z .
And y :
y=180-(z+13)
Got it ?

Answer 7

K !
And for 3th we have :
m2 = -1/m1
Means m for this equation is :
m2=-1/4
We find the m1 = 4 .
So we have this again :
Y2-y=m(X2-x)
we have :
Y2=-3
X2=10
m=-1/4
Got it ?

Answer 8

And for your second :
x=180-(36+63)
And :
x+z=180
If you find x can answer z .
And y :
y=180-(z+13)
x=180-99=81
we had :
x+z=180
81+z=180 =>z=180-81= 99
And y :
180 - 99+13 = 81+13 = 94
y=94
x=81
z=99
Got it ?

Answer 9

Do have any problem ?

Answer 10

@Gracy_KSL
you should first find slope using given two points.i.e.slope=y2-y1/x2-x1
then use point-slope formula i.e. y-(y-coordinate of any of the two points)=slope{x-(x-coordinate of the the point taken earlier)}.

You said that better than me !
Thank you .
