Answer:
(1,0)
Step-by-step explanation:
Hi there!
We want to find the x intercept of the line that passes through the point (3,4) and has a slope of 2
First, let's find the line
We are given both a slope, and a point. We can write the equation of the line in point-slope form, which is
, where m is the slope and
is a point
We do have everything needed to write the equation, let's just label everything to avoid confusion:
m=2

=4
Now substitute those values as the variables that they represent into the equation:

y-4=2(x-3)
Now we have the equation in slope-point form
The x intercept of the line is the value in which the line passes through the x axis. The value of y at this point is 0
So we can substitute y as 0 in the equation to find out the value of x:
y-4=2(x-3)
0-4=2(x-3)
Multiply
0-4=2x-6
Add 6 to both sides
0+2=2x
Simplify the left
2=2x
Divide both sides by 2
1=x
So the value of the x intercept is 1, also written as the point (1,0)
Hope this helps!
Answer:
Step-by-step explanation:
3x + y + 72 = 180
3x + y = 108 .... <em>(1)</em>
2x + y = 90 ..... <em>(2)</em>
(1) - (2)
<em>x = 18°</em>
<em>y = 54°</em>
