Answer:
y = (3/4)x + 2
Step-by-step explanation:
Slope-intercept form is y=mx+b where (x, y) is a point on the linear graph, m is the slope (rise/run), and b is the y-intercept (the y-value at which the graph passes through the y-axis).
Looking at the graph, we can see that the point at which the line crosses the y-axis is (0, 2) which makes it the y-intercept. Thus, the b in the slope-intercept form is 2.
Next, we are looking for the slope of the line. To do this, we can calculate the rise/run of the line by choosing to points on it. Since we already have the point (0, 2), we just need one more.
For example, the point (-4, -1) can be used. The slope can be found by ((y-y)/(x-x)) in which the first y and x values correspond with the first point and that of the second correspond with the second set. So in this case, m = (2-(-1))/(0-(-4)) = 3/4
Plugging in the calculated m and b value in the slope intercept equation, we get y = (3/4)x + 2
The slope of y= 1/2x-7 is always positive because since the slope of this equation is “1/2”, 1/2 is always positive.

Answer:
3.2%
Step-by-step explanation:
-Let r be the simple interest rate per annum.
-Given the total amount after 1 year is 1857.60, the initial amount is 1800
#We use the simple interest formula to find the rate of interest:
Hence, the annual interest rate on the deposit is 3.2%
