- Write the equation for the line through the points (-2, 8) and (7, –10) in the form y = m(x – xo) + yo where m is the slope of the line and (xo, yo) is a point that it passes through. This is sometimes referred to as the point-slope form of the line. y =arrow_forward· Graph. x 2 - 2 2x + y < 3arrow_forwardGraph. (x-3)2/4 + (y-9)2/16 =1arrow_forward
- Write the equation corresponding to the graph of y = 5* after having been translated three units upward, four units to the left, and las reflected over the x-axis. Write your answer without using parentheses. Enter your next step herearrow_forwardwer. What is the slope of the function y 3x + 5x – 7 at (-1,-9).arrow_forwardPart 3 of 5 (c) Use the data points (4, 1.4) and (28, 2.6) to find an equation of the line through these points. Express numbers as decimals or integers. Write the answer in slope-intercept form (y=mx+b). The equation is 0=0 Ś Xarrow_forward
