Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Answer:
d = 15 miles
Step-by-step explanation:
To get to his parents’ house, Ruben would have to drive due north 12 miles.
To get to his grandparents’ house, he would have to drive due east 9 miles.
It is required to find the distance between the parents’ and grandparents’ houses.
First distance is 12 miles and second distance is 9 miles.
So,
So, the distance between the parents’ and grandparents’ houses is 15 miles.
Answer: for -4/3x+4 the y intercept is (0,4) and x is (3,0) the slope is -4/3
for 2/7x+2 the y intercept is (0,2) and the x is (-7,0) the slope is 2/7
Step-by-step explanation:
Answer:intersecting
Step-by-step explanation:
it is intersecting because the lines go inside not side by side or anything else.

Step-by-step explanation:
The first function is a sin function with an amplitude of 2, and a period of 4pi. The -1 moves it down from its original position 1 unit. There is no phase shift here. The normal period of a sin function is 2pi, which means that one revoution of the graph (one Up-down-up to put it in simplest terms) starts at 0 and ends at 2pi. The x/2 means that the value to consider for the period change is 1/2. The formula to solve for a period change is 2pi/that value (most books call it b). So we have 2pi/(1/2), which algebraically solves to 4pi. That means that one up-down-up of the function starts at 0 and ends at 4pi.
That second function doesn't have a b value, so its period is still 2pi. The -5, however, moves the whole graph down 5 units from the original position (which is 4 units below the first graph). The second function also has an amplitude of 2. I hope this helps a bit!
