What is the equation of the line that passes through the points (–2, 2) and (0, 5)?
lana66690 [7]

Answer:

The equation of line is given by

y=\frac{3}{2}x+5

Step-by-step explanation:

We have been given the points (–2, 2) and (0, 5) and we have to find the equation of the line.

Let us first find the slope of the line using the formula

m=\frac{y_2-y_1}{x_2-x_2}

On substituting the values, we get

m=\frac{5-2}{0+2}

m=\frac{3}{2}

Now, using the point slope form, the equation of line is given by

y-y_1=m(x-x_1)\\y-2=\frac{3}{2} (x+2)\\\\y-2=\frac{3}{2}x+3\\\\y=\frac{3}{2}x+5

Therefore, the equation of line is given by

y=\frac{3}{2}x+5

If the equation y=mx+b is used to model a quantity y as a function of the quantity x, why is b considered to be the starting val
blagie [28]

Answer:

This is because even when the quality of the variable x is 0, the value of b still exists and is the starting point for y.

Step-by-step explanation:

To prove this, we start with the base form of the equation and input 0 for x.

y = mx + b

y = m(0) + b

y = 0 + b

y = b
