Answer:
Step-by-step explanation:
Points (0,-3) and (-2,0)
Slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{0-(-3)}{-2-0}[/tex] = [tex]\frac{3}{-2}[/tex] = [tex]-\frac{3}{2}[/tex]
Slope-intercept formula: y = mx + b
[tex]y=-\frac{3}{2}x+b[/tex]
[tex]y=-\frac{3}{2}x+b\\-3 = -\frac{3}{2}(0) + b\\-3 = 0 + b\\-3 = b\\ \\ y = mx + b\\y = -\frac{3}{2}x-3[/tex]
Hope that helps!
