Answer:
8.6
Step-by-step explanation:
The x-intercept of a line is when the y coordinate is equal to 0. So, the x-intercept would be (0,-7).
The y-intercept of a line is when the x coordinate is equal to 0. So the y-intercept would be (-5,0).
To find the equation of a line, you need the slope and the y-intercept.
We already know the y intercept is -5. The equation for a line is:
Y=mx+b
m stands for slope
b stands for the y intercept.
To find the slope, use the equation-
y1-y2
--------
x1-x2
Another way to say that is the change in y over the change in x.
Plug in the the 2 coordinate points you know, which are (-7,0) and (0,-5).
0+5
-------,
-7-0
5/-7.
The slope is 5/-7
The Y intercept is -5
The equation of the line is y= 5/-7x -5
The coordinate point for the x intercept is (-7,0)
The coordinate point for the y intercept is (0,-5)

Answer:
y = (1/2)x + 2
Step-by-step explanation:
Find the slope:
Take the rise over run to find this- For every unit it goes up, it goes two units across, so it will be (1/2)
Find the y-intercept:
This is the value of y where the line intersects the y-axis- (0,2), so 2
Substitute these values in for m and b:
y = mx + b
y = (1/2)x + 2
Hope that helps! :)
