Answer:

y = -5x - 18.

Explanation:

The point-slope form of the equation of a line is given by:

y - y1 = m(x - x1)

where m is the slope of the line, and (x1, y1) is a point on the line.

We are given that the line passes through the point (-7, 17) and has a slope of -5. Thus, we can substitute these values into the point-slope form equation to get:

y - 17 = -5(x - (-7))

Simplifying the right-hand side of the equation:

y - 17 = -5(x + 7)

y - 17 = -5x - 35

Finally, adding 17 to both sides of the equation, we get the slope-intercept form of the equation:

y = -5x - 18

Therefore, the equation of the line that passes through the point (-7,17) with slope -5 is y = -5x - 18.

Answer:

y - 17 = - 5(x + 7)

Explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = - 5 and (a, b ) = (- 7, 17 ) , then

y - 17 = - 5(x - (- 7) ) , that is

y - 17 = - 5(x + 7)
