Help! Here's a graph of a linear function. Write the equation that describes that function. (If blurry zoom in.)

(Express it in slope-intercept form.)

y=1/2x-5

Step-by-step explanation:

the formula is y=mx+b and the slope is m. So we find what the slope is and see that the line goes up once and over twice 1/2. and then the y intercept is -5

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
