Answer:
Explanation:
Slope-intercept form is written out as y=mx+b with "b" being the y-intercept of a line or curve on a graph.
One of the ordered pairs (0, -9) has the value of coordinate Y when X is equal to zero. This in fact, is your y-intercept: -9.
To figure out the slope of two points on a graph we first need to take the coordinate values and separate them into two categories (X and Y)
X1 = -3
X2 = 0
Y1 = -14
Y2 = -9
To calculate the slope, use the formula: (Y2-Y1/X2-X1) where / denotes the division between the two axis. This is the change in Y over the change in X.
After we plug in the values, we get -9 - (-14) / 0 - (-3) = 5/3
Remember that subtracting a negative number makes the sum positive.
Slope: 5/3
Y-Intercept: -9
Equation: (5/3)x-9
