Will give brainiest and 60 points if you show work so i can understand these. 1. find the slope of the line that passes through the points (-1, 2), (0, 5). 2. suppose y varies directly with x, and y = 15 and x = 5. write a direct variation equation that relates x and y. what is the value of y when x = 9? 3. write an equation in slope-intercept form of the line that passed through (-3, 4) and (1. 4). 4. use point-slope form to write the equation of a line that has a slope of 2/3 and passes through (-3, -1). write your final equation in slope-intercept form. 5. write the equation in standard form using integers (no fractions or decimals): = −2/3 − 1 6. write an equation of the line that passes through (2, -1) and is parallel to the graph of y = 5x – 2. write your final equation in slope-intercept form. 7. write an equation of
