Point 1 =(x1,y1)= (-2,-5)
Point 2 =(x2,y2)= (4,4)
Slope intercept form:
y=mx+b
Where
m= slope
b= y-intercept
Apply the slope formula:
![m=\text{ }((y2-y1))/((x2-x1))](https://img.qammunity.org/2023/formulas/mathematics/high-school/n8gf8q0qffwpf17o1vr1l9ucbd8ut4jhvr.png)
Replacing:
![m=\text{ }(4-(-5))/(4-(-2))=(4+5)/(4+2)=(9)/(6)=(3)/(2)](https://img.qammunity.org/2023/formulas/mathematics/high-school/lvooqmd00ywp3uwxo9tq87133hnbgnqz35.png)
So far:
y= 3/2x+b
replace x,y by the coordinates of 1 point (4,4), and solve for b:
4= 3/2(4)+b
4= 6+b
4-6 = b
-2 =b
Final expression:
y= 3/2x-2
