Stepbystep explanation:
Mark the two points (1,7) and (1,1) on the graph. Then draw a straight line between them. To determine the equation that goes through these two points, we can use the two given points to find the slope of the line. The standard form of a straight line equation is
y = mx + b,
where m is the slope and y is the yintercept (the value of y when x = 0).
Slope is also known as the "Rise"/"Run"  the change in y divided by the change in x. We can use the two points to calculate this:
Rise (1(7) = 8 Run = (1  (1) = 2
The slope is therefore (8/2) or 4.
y = 4x + b
We can find b by entering either of the two points in y = 4x + b and solve for b. I'll use (1,1) since I have my 1's multiplication table memorized
y = 4x + b
1 = 4(1) + b
b = 3
The straight line equation that connects the two points is
y = 4x + 3
You can graph this equation (e.g., on DESMOS) to see how it intersects the points. [Attached]
The coordinates of the y intercept are (0,3).

The coordinate of the yintercept of the line is (0, 3)
Equation of a line
The equation of a line in slopeintercept form is expressed as y = mx + b.
where:
 m is the slope the line
 b is the yintercept
Given the coordinate points (1, 7) and (1, 1).
Get the slope
[tex]m=\frac{y_2y_1}{x_2x_1} \\ m=\frac{17}{1(1)}\\ m=\frac{8}{1+1}\\ m=\frac{8}{2}\\ m=4[/tex]
Get the yintercept:
Recall that y = mx + b
Using the coordinate point (1, 1) and m = 4
1 = 4(1) + b
1 = 4 + b
b = 1 + 4
b = 3
The equation of the line is y = 4x + 3
Get the yintercept:
The yintercept occurs at the point where x = 0
y = 4(0) + 3
y = 0 + 3
y = 3
Hence the coordinate of the yintercept of the line is (0, 3)
