PLEASE HELP WILL MARK BRAINLIEST!!!!

Answer:
y = -5x + 20
Step-by-step explanation:
Lets start with the first given values for x and y
(2,10)
Lets try out the first equation
y = 5x + 4
y = 5(2) + 4
y = 14
This equation wouldn't work because the y value is not 10 when the x value is 2
y = 5x + 20
y = 5(2) + 20
y = 30
This equation doesn't work either
y = -5x + 20
y = -5(2) + 20
y = -10 + 20
y = 10
This would be the correct equation since your y value is 10 when the x value is 2
Answer:
y = -5x + 20
Step-by-step explanation:
(2,10) and (3,5)
Slope = (y-y)/(x-x)
(10-5)/(2-3) = 5/-1 = -5
y-intercept (any point) = y - (slope times x)
y-intercept = 5 - (-5)(3) = 5 + 15 = 20
