Respuesta :

y - y1 = m(x - x1)
slope(m) = 4/5
(-2,1)....x1 = -2 and y1 = 1
now we sub
y - 1 = 4/5(x - (-2) =
y - 1 = 4/5(x + 2) <===

Answer:

[tex]y-1= \frac{4}{5} (x+2)[/tex]  

Step-by-step explanation:

Using point-slope intercept form:

The equation of line is given by:

[tex]y-y_1 = m(x-x_1)[/tex]              .....[1]

where,

m is the slope of the line and [tex](x_1, y_1)[/tex] is the point on the line.

As per the statement:

A line with slope 4/5 that contains the points (-2,1)

⇒m = [tex]\frac{4}{5}[/tex] and [tex](x_1, y_1)=(-2, 1)[/tex]

Substitute these values in [1] we have;

[tex]y-1= \frac{4}{5} (x+2)[/tex]  

Therefore, [tex]y-1= \frac{4}{5} (x+2)[/tex]  is the point slope form of a line with slope 4/5 that contains the points (-2,1).
