Determine the equation of the line thatpasses through (0, 2) and (4, 5). Put inslope-intercept form.

Sagot :

Given:

Point ( 0, 2) and (4, 5)

The coordinates are:

x₁=0 y₁=2 x₂=4 y₂=5

First, we need to find the slope(m) using the formula below:

[tex]\text{slope(m)}=\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values and evaluate.

[tex]\text{slope(m)}=\frac{5-2}{4-0}=\frac{3}{4}[/tex]

Next, is to find the intercept(b) by substituting m=3/4 x=0 and y=2 into y=mx+b and then solve for b.

2 = 3/4 (0) + b

b=2

We can now proceed to form the equation by substituting the values of m and b into y=mx + b.

Hence, the equation of the line is:

[tex]y=\frac{3}{4}x\text{ + 2}[/tex]
