wright the slope-intercept form of the equation of the line though the given points through:(4,4)and (3,5)
Get the slope: y2-y1/x2-x1
m= (5-4)/(3-4)
m= -1
formula y-y1=m(x-x1)
pick a set of points.
y-4=m(x-4)
y-4=(-1)(x-4)
y-4=-x+4
y=-x+8
There is the equation.

To find the slope-intercept form of the equation of a line passing through two given points, we can use the formula:
y = mx + b
Where:
m is the slope of the line
b is the y-intercept of the line
To find the slope (m), we can use the formula:
m = (y2 - y1) / (x2 - x1)
Given the points (4,4) and (3,5), we can substitute the values into the formula:
m = (5 - 4) / (3 - 4)
m = 1 / (-1)
m = -1
Now that we have the slope, we can substitute it into the slope-intercept form equation:
y = -1x + b
To find the y-intercept (b), we can substitute one of the given points into the equation. Let's use the point (4,4):
4 = -1(4) + b
4 = -4 + b
b = 8
Now we have the value of b, so we can write the equation of the line in slope-intercept form:
y = -x + 8
