pls helpAnswer correcltyQuestion 1:What is the first step to writing an equation in slope-intercept form using the given points: (-1, 0), (-2, -2). A) Use point-slope form B) Substitute -1 for x and 0 for y in y = mx + b C) Find the slope using the slope formula y2 - y1x2 - x1D) Find the slope using the slope formula y = mx + b Question 2:The events x and y have a correlation coefficient of r= 0.02. What is the relationship between x and y? A) The events have a strong negative linear correlation. B) The events have a strong positive linear correlation. C) The events have a weak negative linear correlation. D) There is little or no linear correlation. Question 3:Camille asked five of her friends how long they studied for the last math test and what grade they received.

Tisha and her academic team are working to go to state finals. They must have a certain number of points, T, to advance. They have had three local matches, a, b and c, and will attend a district match. District match points count for twice the number of points than local matches do. Choose the equation that would help Tisha find how many points they need to earn in the district match, d, to advance. d = T - a - b - c all over 2 d = T over 2 - a - b - c d = T + a + b + c all over 2 d = 2(T − a − b − c)
