Answer:
y = x + 7
Step-by-step explanation:
The slope-intercept form of a line is:
y = mx + b
where m is the slope and b is the y-intercept.
Looking at the graph, we can see that the line intersects the y-axis at y = 7. So 7 would be our y-intercept.
To find the slope, we would divide the rise of the line by the run. Or m = rise/run. From looking at the graph, we can see that for every 1 unit the line moves in the x-direction, the line moves in the y-direction by 1 unit. Therefore, the rise would be 1 and the run would be 1. 1/1 = 1 so the slope of the line would be 1.
Plugging in 7 for b and 1 for m into the equation for the slope-intercept form, we get:
y = x + 7
So that would be the equation for the line in slope-intercept form.
I hope you find my answer and explanation to be helpful. Happy studying.

Answer:
y = 3x - 5
Step-by-step explanation:
Points on given line: (-3, 2), (0, 1)
m1 = slope of given line; m = slope of perpendicular
Slope of given line = m1 = (y2 - y1)/(x2 - x1) = (2 - 1)/(-3 - 0) = 1/(-3) = -1/3
The slopes of perpendicular lines have a product of -1.
m1 * m = -1
-1/3 * m = -1
m = 3
Slope of perpendicular: m = 3
Point on perpendicular: (3, 4)
y - y1 = m(x - x1)
y - 4 = 3(x - 3)
y - 4 = 3x - 9
y = 3x - 5
Answer: y = 3x - 5
Rounded to nearest ten--- 950
Rounded to nearest hundred--- 900
A trick you can use for rounding-------- 5 or more, raise the score; 4 or less, let it rest.
