What is the equation of the line that passes through the point (4, -4) and has a
slope of –3/4?

y=-3/4x-1

Step-by-step explanation:

y=mx+b; y is the y coordinate; m is the slope; x is the x coordinate; you have to find b. So you replace all the numbers out which is given to you;

-4=-3/4(4)+b (you multiply -3/4 by 4 and get -3)

-4=-3+b (you add 3 to both sides and get -1)

-1=b (you now found b so plug it into the equation)

y=-3/4x-1

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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.
