look at this graph. write the equation for the relationship shown in the graph. start your equation with y…

Explanation:

Step1: Find the slope

The line passes through points (0, 50) and (50, 100). The slope $m$ formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. So $m=\frac{100 - 50}{50-0}=\frac{50}{50}=1$.

Step2: Find the y - intercept

The line intersects the y - axis at the point (0, 50), so the y - intercept $b = 50$.

Step3: Write the equation

The slope - intercept form of a line is $y=mx + b$. Substituting $m = 1$ and $b = 50$ gives $y=1x+50$ or simply $y=x + 50$.

Answer:

$y=x + 50$
