Answer:
Step-by-step explanation:
The y-intercept is the value of y when x=0.
8(0) - 3y = 0
y = 0
y-intercept = 0
Independent variables means it is not affect by the other variables(be it unknown or the dependent ones).
Example being the number of hours you take to travel from one place to another.
But a dependent variable's value is affected by the independent variables. So taking the earlier example, the speed you travelled at is based on the time taken and the distance of the place from the other.
Answer:
D. On a graph, plot the line y = −x + 1, which has y-intercept = 1 and slope = −1, and y = 2x + 4, which has y-intercept = 4 and slope = 2, and write the coordinates of the point of intersection of the two lines as the solution.
Step-by-step explanation:
Each equation is in the slope-intercept form:
y = mx + b
in which m is the slope and b is the y-intercept.
__
Matching this form to the given equations, you find that ...
first equation: m = slope = -1; b = y-intercept = 1
second equation: m = slope = 2; b = y-intercept = 4
Comparing these values to those in the answer choices makes it clear which one is correct (see above).
Answer:
Top left
Step-by-step explanation:
A function describe a relation between elements of a set (domain) to <u>one and only one</u> element of a second set (range). The key word is the "one and only one: it means that every time I put a value into the function (imagine it as a box) it returns either no value, or one value.
That lead us to the "vertical line test" or "ruler test". If you scan the images with a vertical line (you can use the edge of a piece of paper, a pen, whatever you want) and slide it across the plane, the moment you touch the graph in two (or more!) points, you can rule out that it's not a function. That's what happens with all graphs besides top left.
