Answer:
-7
Explanation:
You want the y-intercept of the equation y = 10x -7.
Y-intercept
The y-intercept is the point where the graph crosses the y-axis. At that point, the value of x is 0.
Substituting x=0 into the equation gives ...
y = 10·0 -7 = 0 -7 = -7
The y-intercept is the point (0, -7), or -7 on the y-axis.

Additional comment
The form of the given equation is "slope-intercept" form:
y = mx +b
where m is the slope of the line, and b is the y-intercept. Comparing this to y = 10x -7, we see that b = -7. The y-intercept is -7.
