Answer:
Step-by-step explanation:
We are given two points, the y - intercept and the x - intercept.
The y - intercept being: ( 0, -7 )
The x - intercept being: ( 1, 0 )
The equation of a line in slope - intercept form is:
y = mx + b, where m is the slope and b is the y - intercept.
We already have the y - intercept. So far we have:
y = mx - 7
What we're missing is the slope.
To find the slope, we can use this formula:
, where and are the x - coordinates of both points and and are the y - coordinates of both points.
We now have the missing piece, the slope, so the equation now is:
The y-intercept is: y = 7x - 44
Subtract 5 each play so go backwards from zero and you should finish at -15
