If the gradient between the points (3,-7) and (4,y) is equal to 3/5, find y

y=-38/5

Step-by-step explanation:

the gradient (slope) equation is y2-y1/x2-x1. So, we know that -7-y/4-3 = 3/5, so -7-y/1 = 3/5, Finally, -7-y=3/5 so -y = 38/5, and y = -38/5

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
