In my religion, I believe life is a test from God.
13\20 x 60\x
cross multiply
13x=1200
x=92.3
Y = x + 1
y = 1/2x + 3
x + 1 = 1/2x + 3
x - 1/2x = 3 - 1
1/2x = 2
x = 2 / (1/2)
x = 2 * 2/1
x = 4
y = x + 1
y = 4 + 1
y = 5
so ur solution is : (4,5)
Answer: a. the slope is -2/5 and the y-intercept is -1/3
Step-by-step explanation:
Find the slope by finding the difference in x-values divided by the difference in y-values
(1/4 ,-13/30) and (-3/4, -1/30) are useful values
-13/30 --1/30 = -12/30 = -2/5 is the rise
-1/4 - -3/4 = 1 is the run (-2/5)/1 Division by 1 leaves the original numerator)
the slope is -2/5
To find the y intrcept, substitute the y and x values from any given coordinate into the slope intercept form and solve for b
y= mx + b
-3/5 = (-2/5)(2/3) + b
-9/15 + 4/15 = b
-5/15 = b
-1/3 = b This is the y-intercept
