Answer:
y = 6x + 4
Step-by-step explanation:
Find the slope (m) of the line that contains (1, 10) and (0, 4).
Slope = ∆y/∆x = (4 - 10) / (0 - 1) = -6/-1
Slope (m) = 6
Find the y-intercept (b):
y-intercept (b) is 4 because it is the value of y when x = 0.
To write the equation in slope-intercept form, substitute m = 6 and b = 4 into y = mx + b.
Thus:
y = 6x + 4
Answer:
112
Step-by-step explanation:
2(-3+63)-4(2)

78,80,82,84,86,87,87,89,94,95
86+87/2 = 86.5
Answer:
5/7
Step-by-step explanation:
We have two points ( 2,-2) and (9,3)
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 3- -2)/( 9-2)
= ( 3+2)/(9-3)
= 5/7
