I think it is two. I’m sorry if I am wrong.
Answer:
90/13, 45/13
Step-by-step explanation:
![- 2 = x \\ 7x + 9y = - 45 \\ \\ 7 \times ( - 2)y + 9y = - 45 \\ y = 9 \\ \\ 7x + 9 \times 9 = - 45 \\ x = - 18 \\ (x.y) = (- 18.9) \\ \\](https://tex.z-dn.net/?f=%20-%202%20%3D%20x%20%5C%5C%207x%20%2B%209y%20%3D%20%20-%2045%20%5C%5C%20%20%5C%5C%207%20%5Ctimes%20%28%20-%202%29y%20%2B%209y%20%3D%20%20-%2045%20%5C%5C%20y%20%3D%209%20%5C%5C%20%20%5C%5C%207x%20%2B%209%20%5Ctimes%209%20%3D%20%20-%2045%20%5C%5C%20x%20%3D%20%20-%2018%20%5C%5C%20%28x.y%29%20%3D%20%20%28-%2018.9%29%20%5C%5C%20%20%5C%5C%20)
Simplify:

Answer:y=1/2x+3
No Parenthesis or anything.
You just need to list literally all the numbers under 100 (not including negative numbers) that aren’t a multiple of 3
Y-intercept would be (0,-2)
The equation of a line in
slope-intercept form
is.
∙
y
=
m
x
+
b
where m represents the slope and
×
×
b, the y-intercept.
y
=
1
3
x
−
2
is in this form.
⇒
slope
=
1
3
and y-intercept
=
−
2
plot the point
(
0
,
−
2
)
using the slope, from -2 go up 1, across 3 to the right and
mark the point, that is (3,-1). Repeat for another point.
and draw a straight line through the points
