how do i write an equation with only that?

Given information :
m=1 (3,3)
how do i write an equation in slope intercept form?
Answers:
Assuming you need a line equation, find the slope (5-4)/(3-2) = 1
Slope intercept form is y = mx + b where m= slope and b= y-intercept. So you know it's y = 1x + b.
Plug in a known point, either one, for x and y:
5 = 1(3) + b
so b must be 2 and the answer is y = 1x + 2 or just y = x + 2
Similarly, on the other one, you know it's y = 1x + b
3 = 1(3) + b so b = 0 and answer : y = 1x + 0 or just y = x
Hope that helps
First find the slope. slope formula (y2 - y1)/(x2 - x1)
(5-4)/(3-2) = 1
In point slope form you get: y - 4 = 1( x - 2) or y - 4 = x - 2
If you want to rewrite this in slope intercept form ( y = mx + b), add 4 to both sides: y = x + 2
For the second problem, there are two ways to do it:
1st method: Write in point slope form
y - 3 = 1 (x - 3) or y - 3 = x - 3
Add 3 to both sides, y = x
2nd method: Plug point and slope into slope intercept form to find b
y = mx + b
3 = 1(3) + b
3 = 3 + b
0 = b
Thus your equation is y = 1x + 0 which simplifies to y = x
