Answer:
y = 3x + 2
Step-by-step explanation:
Slope-intercept form: y = mx + b
Slope formula: 
Given points: (-1, -1), (1, 5)
(-1, -1) = (x1, y1)
(1, 5) = (x2, y2)
To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.
First, let's find the slope. To do this, input the given points into the slope formula:
Simplify:
5 - (-1) = 5 + 1 = 6
1 - (-1) = 1 + 1 = 2
The slope is 3.
To find the y-intercept, input the slope and one of the given points(in this example I'll use point (1, 5)) into the equation and solve for b:
5 = 3(1) + b
5 = 3 + b
2 = b
The y-intercept is 2.
Now that we know the slope and the y-intercept, we can write the equation:
y = 3x + 2
Mark ran 28.2 miles less than Cody, but Mark ran 12.4 miles, so Cody ran 40.6 miles.
miles Cody ran - miles Mark ran = 28.2
C - 12.4 = 28.2
C = 40.6 miles

Answer:
d = 1
Step-by-step explanation:
For the number to be divisible by 9, the sum of digits must be a multiple of 9. The sum of digits is ...
4 + 3 + 7 + d + 0 + 3 = 17 +d
The nearest multiple of 9 is 18, so we have ...
17 +d = 18
d = 18 -17 = 1
The value of d is 1.
