Answer:
y = 9x - 7
Explanation:
Slope-intercept form is y = mx + b
Y-intercept is where x = 0. In this instance, when x = 0, y = -7 (0, -7)
So at this point we know b = -7.
Then, take one of the values of x, such as 1, as well as the corresponding value of y and plug in. When x = 1, y = 2 (1, 2)
2 = m(1) - 7
Solve for m (slope)
2 = m - 7
Add 7 to both sides to get m alone.
9 = m
Now we know the slope, and the y-intercept, so we can fill in the equation for slope-intercept form for this linear function.
y = mx + b
y = (9)x + (-7)
y = 9x - 7
