Answer:
y=3x+3
Step-by-step explanation:
slope is 3 because rise over run. Rise is 3 and run is 1. 3/1 is 3. and b= y-intercept and the poiunt wehre the line intercepts the y axis is 3. so your answer is y=3x+3
Answer:

Step-by-step explanation:
Given:
The two points on the line are
and
.
The slope of the line joining two points
and
is given as:

Here, 
∴ 
Equation of line with a point
and slope
is given as:

Plug in -2 for
, 3 for
and -7 for
. This gives,

Therefore, the equation of the line in vertex form is
.
Answer:
The value of x is the value where the line crosses the x-axis!

Hope this helps!!
Please tell me if I have made a mistake!!
I enjoy learning from them:)
To find the value of x let's make the situation a bit easier
3x+10+70=180
3x+80=180
3x=180-80
3x=100
x = about 33.33
Surprisingly, a one-step equation <em>is </em>that simple; it's just an equation that takes one step to solve. So yes, 3 + 4 = 7 would be one you could do. You could also do a simple multiplication or division problem if you'd like, for instance you could do 4*3=12, or 12/4=3. Hope I helped!
