Answer:
Y-int = -45, X-int =-11.25
Step-by-step explanation:
Please read this before moving on :)
An intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+b, where m is slope and b is the y-intercept.
We know that equation of a line is y=mx+b. To find the value of the x-intercept of the line we simply need to put the value of the y as 0.
Using the Slope Equation : Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
1 - Finding the Slope
2 points; (0,-40), (-10,0)
0-(-40)/(-10)-0 = 40/-10 = -4
2 - Y-INT
Y=MX+B
Y=MX+(-45)
Y=MX-45
Y-int = -45
3 - X-INT
Y=MX+B
0=(-4)x+-45
45=-4x
X-int =-11.25
