What is the equation for the line? enter your answer in the box.

y = -4x + 5

Step-by-step explanation:

The equation of line y = mx + b, where "m" is the slope and "b" is the y-intercept.

From the given graph, we find the y-intercept (b) = 5

To find the slope, let's take two points from the given line.

(0, 5) and (3, -7)

Slope = (y2 - y1)/(x2 - x1)

= (-7 -5)/(3 - 0)

Slope(m) = -12/3

Slope (m) = -4

Therefore, the equation of the line y = -4x + 5

Hope this will helpful.

Thank you.

(a)

4x + 3y = 23

5x + 2y = 20

(b)

4x + 3y = 23   ⇒   -2(4x + 3y = 23)   ⇒    -8x - 6y = -46

5x + 2y = 20   ⇒    3(5x + 2y = 20)   ⇒   15x + 6y = 60

                                                                 7x          = 14

                                                                   x          = 2

5x + 2y = 20

5(2) + 2y = 20

 10 + 2y = 20

        2y = 10

         y = 5
