A linear function has the same y-intercept as x +4y= 16 and its graph contains the point (3,5). Fill in the blank to find the y-intercept.

To find the y intercept of x+4y=16, let us convert the equation to slope-intercept form, that is, y=mx+b

To get the equation in slope-intercept form, we try to isolate y

To isolate y in x+4y=16, let us first try to get rid of x from left side

So, Let us subtract x from both sides

x-x+4y=-x+16

0+4y=-x+16

Or, 4y=-x+16

Now, to isolate y we must try to get rid of 4

So, let us divide by 4 on both sides

1y=

y=x+4

If we compare y=x+4 to y=mx+b

b, or y intercept=4

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
