Explanation:
The slope-intercept form of an equation of a line:
![y=mx+b](https://img.qammunity.org/2020/formulas/mathematics/high-school/8nudzfk4b5l0arb9iixag2w8am6zn99zlr.png)
m - slope
b - y-intercept (0, b)
The formula of a slope:
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fc06wy5n2hf2a0hmyba6df4ibmxk1cn53a.png)
From the graph we have two points (0, 4) → b = 4, and (3, 5).
Calculate the slope:
![m=(5-4)/(3-0)=(1)/(3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/odv40hfdahk9nqskjnxphznjvnv7isgntt.png)
If you want the equation of a line, then put the value of m and b to the equation of a line:
![y=(1)/(3)x+4](https://img.qammunity.org/2020/formulas/mathematics/college/4ptvmendls0oztp0o4ssvbr2yepcuz10mn.png)
