A line with slope -3 passes through the points (5,2) and (9,y). Find y.
plz help!

y is 10

Step-by-step explanation:

first take your imformation and put it into the y intercept from.

Which is y=mx+b

so take the cordinates (5,2) and put it into the y-intercept form.

the 5 is x and the 2 is the y, so

2=m*5+b

Then take the slope of -3 and put it in the y-intecept from

2=-3*5+b

then solve for b

2=-3*5+b

2=-15+b

+15  on both sides

17=b

now you know the equation of the line is

y=-3x+17

now plug in your x to find the y of that cordinate

on the line.

y=-3*9+17

solve

y=-3*9+17

y=-27+17

y=10

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
